Scotty's 1965 Chevy SportVan Deluxe Travel Cruiser

You're right! I didn't realize that even though the 200R4 is shorter overall, it's mount is actually further back than on the 700R4. The dimensions on the left are for the mount:



Interesting. Even though the 700R4 requires shortening the driveshaft, it's tranny mount is very close to the same position as the Powerglide that came in these vans.

So Don, I see you've been hanging the 3rd Gen crossmember the same way as my mount here does, coming straight down from between the stock van crossmember/sub frame. Maybe the trick would be to hang the mount for a 200R4 behind the stock crossmember instead of inside it.

I'll take another look at my mount in the morning.

Transmission Ratios:
GM * * * * *1st. ***2nd. * * 3rd * * *4th
TH350 * *2.52 * *1.52 * *1.00. * * N/A
200r4. * * 2.74 * *1.57 * *1.00 * * 0.67
700r4. * * 3.06 * *1.62 * *1.00 * * 0.70

This Corvette page has a good discussion about how little the difference in these gear ratios comes out to. Plus they have the formula to figure out rpm's based on these.

I would think that if it needed to be moved forward or back that a piece of flat iron with holes drilled to offset either direction would make the mount usable. Without seeing how and where it would go I cant tell exactly but it should be easily modified to use. Seems like a good starting point at least.

Want to ask a question about your diagram VANagain. So the TH350 had a possibility of 3 different tail sections? Not sure what the 66 has in it, but there is a possibility if I was to swap the 700 in that I might have to lengthen it if they put in the largest tail section?

I don't know for sure. You'll have to measure your TH350's tail shaft and see which one of those you have and then compare to the length of the 700R4.

I should point out that changing the length of your driveshaft is not that big of a deal. They charge about 100 bucks for it and can also set you up with a different yoke if the tranny shaft splines are different. I needed that too on mine.

I had a look under the van today and it looks like that crossmember will hit the exhaust if I hang it behind those frame rails. Maybe extending the mount with some flat stock is the answer.

I was thinking the same thing. In fact, I've seen many aftermarket crossmembers that have a flat piece welded to them in the middle that hangs over. Makes it easier to get to the bolts too!

Any more info on how they set up the lock-out circuit on your 200R4?

Haven't had a chance to look at it yet, that's my next project. I've been diving into my brakes this weekend.

I got one side test fit and I'm finding out that the Nova steel rims I got are probably not going to fit. I tried grinding down extra casting on the calipers and in the insides of the rim, but I think it's just too tight. They fit on the car's discs at the junkyard, but I guess this setup is slightly larger.

Gonna look for some good looking rims on CL. I'd like to find some aftermarket 14s that fit seeing as how I just bought brand new tires. But if I can find 15s with decent tires, I might do that.

I also found these, but it says the only accept full wheel hubcaps. Im wondering if I can make up a bracket to mount my dog dish caps.
Rims

Here are photos showing two ways my tranny crossmember could be mounted. Behind the stock crossmember might line up better with the 200R4.

Got all the plumbing mocked up for my disc brakes over the weekend. VanAgain stopped by on Sunday and we came up some ides to design a pretty trick hanger for my new 2004R transmission!

Thought I would post this in my thread to keep a good log of what I got going on with my van.

Good news for people like me who want to keep their stock style 14" rims and install disc brakes. I am using the M1 Brackets using the Nova one piece rotors.

I ordered Wheel Vintiques 62 series 14 x 6 rims from Summit's ebay site with free shipping. I test fit them tonight and they clear with plenty of room to spare and no grinding. My dog dish hubcaps fit right on there too. These have the opened up insides like M1D has talked about in some of the disc brake threads.

Sorry I missed it...Coulda met my doppleganger…

Good news is I finished my disc brakes and I tell ya, it sure makes a world of difference. Well worth it! From the outside it doesn't look like I even touched the brakes (which is what I had planned!)



Now on to my transmission!

I'm really enjoying this thread and the van's backstory. Those painted wheels kick all kinds of ass.

VanAgain's driveway was feeling a little lonely with his van still in the body shop, so I took its place yesterday and we started fabricating a custom hanger for my 2004R transmission. This design will utilize the same hanger style mount and location as the original powerglide.

We finished the bottom portion that will mount to the tranny, then once we get it in place, we can get the final position of the upper rubber mounted hanger. This will be a strap that goes up and over a cylinder that is rubber mounted to the frame.

I like the mount so far, looks really beefy.

We had a fun day making that tranny hanger! It came together real well. Since the 200R4 doesn't have a bolt-on tailshaft housing, we had to use the other holes that were there. There's a tab with a big hole on the right side of the tranny and a smaller tab on the left that we drilled a hole in. And then of course the two threaded tranny mount holes at the rear.

Here's the complete design that I drew in Google Sketchup:



The strap over the top of the cylinder will be one piece (ignore that line) that we cut to fit when the tranny is jacked up in place. (Or it could be just two straight pieces welded to the sides of the cylinder.)

This kind of hanger takes up so little space. There's no need for the rubber tranny mount on the bottom, it can be just metal to metal because of the rubber in the cylinder at the top. Camaro leaf spring rubber is a good fit.

If anyone else wants to make something like this, I've got a lot more of that steel tube!

Had a bit of a scare with my passenger seat almost catching on fire (the original padding in these seats is made of burlap and wool batting that is just begging to go up in flames) so I decided to put in some Miata seats, at least until I get my old one reupholstered....Although these are so comfy, I might not even bother. Plus, these somehow don't look too out of place in the van.

I got both seats for $30 at the junkyard. They're in decent shape, but I can always just plop a new one in if I find some better one. These have the spots for headrest speakers as well which I might install.

(sorry for the crappy phone pics, will get some better ones up soon, and show my brackets as well)





Looking around the junkyard, I thought these 80's Toyota Tercel 4WD Seats would work well. Kinda funky, but I like the grab handle, and the narrow back portion...cool upholstery too!

Finally put up a makeshift headliner. Had a hard time finding a material that would follow the curve of the original headliner divider. I ended up using this stuff called "Plast-Tex" from Home Depot, that's used for commercial bathroom or kitchen walls. It's flexible, easy to cut and trim, but it's rigid enough to hold it's shape.

Looks pretty good I think!

Looks great!!!

comming along nicley.

Yeah , It looks really good!!

Scotty,I have been keeping up with your progress very nicely done.You will be back cruising around in your very nice ride real soon! Bill

Yeah dude, everything youve done kicks much butt.
