Can anybody help me out with a measurement?

Hi Everyone,

I posted on here years ago about a 4x4 conversion project that for various reasons stalled for a long time. I'm back at it and need to build a new doghouse/engine cover from basically scratch.

Anybody with a 2nd gen Chevy mind measuring the height of the "shelf" on the doghouse where the seat bolts down? My van is not on level ground which is a bummer so having this measurement will help end up with a level seat while cruising! Looking for the distance between the floor and the mounting surface for the inboard side of the driver's seat. If I'm correct both sides are the same. My van has the same style seat on both sides, not the removable jump seat.

Thanks in advance, and happy wrenching everyone!

Sorry I was going to go out & check when you posted it(forgot)
But did go out today
I got 11 & 1/2 from top of floor to where  seat mounts
This is on 2nd gen. Hope it helps (better late than never )

Thanks Savage!! If the weather holds out I will be back on this part of the project soon. Have a great New Years!

If need anything else just ask
How about some pics of your van project?


Here some of my  G-20 108

This is what it looked like when it came from CA

Here's one of the interior after I cut out the doghouse and another from a long time ago right after the body was put on the 4x4 chassis (1987 k-10, shortened) and I tried some nice wheels and tires I had to see what it would look like:





I'll see if I can get a few more to upload so you can have a look.  Your G-20 looks great by the way.  Great job going from the before pic to now!!

Pretty sure that mine will end up white too (or at least a majority white) when I get to painting.  Also jealous that yo have a 108 - that extra 18" would have solved SO MANY driveline angle problems!!!

This is what it looked like when I got it back from my friend who shortened the k-10 frame and married the van body to it.  Aside from some different tires and wheels it still looks the same on the outside! (dirtier, and some more surface rust but pretty much the same...)

I'd recommend making those doghouse side steps no taller than the wheel wells if you can because seat pad height is an issue in these vans...

Hi Don,... good call! I hope that with Savage's measurement and a bit of eyeballing and mocking up the seat will remain at factory height. Then just need to make sure the new seat foams aren't too thick. Does anyone offer direct fit replacement seat vinyl?
