Wheel Cylinders

After running into a disagreement with a bleeder screw, I went shopping for rear wheel cylinders on the 69 A. The 2 that exist in this state through my local auto parts store are 48$ apiece, Ona whim I had them look up wheel cylinders for a 69 D100, 9 $ apiece. Okay my question is this will the slightly larger bore of the D100 cyl make a beans worth of difference in the function of the brakes. The stock is 13/16's" these must be at least 7/8". other than that I cant see a difference.

Joe... I replaced my 13/16" with 15/16" on the '68 van and haven't had any problems. Here are the numbers I have for the right ones for $10 each. I got mine from napa about a year ago, took about a week for them to come from there out of state warehouse. The lines were a real "muther" to tighten, I think I ended up using a wrench from my ignition wrench set to bleed them.

Thanks Duane, The ones I picked up today are the 78734#. I was hoping to do a Uber cheap rehone and puck thing but this 1 bleeder was busted off before I got to it, none of my tricks worked.lol

I bet the parts jockey looked at you like you were crazy to even think about rebuilding them.

If a person was worried about being"stock" and that 48 $ is real it would definately be worth not tossing them if they could just be honed out. I've got a stash of NOS rubber cups for small cylinders like that is the only reason I even thought about it.

They are about $50 here as well, I've priced them recently. A rebuild kit is about $7, I ended up honing mine but the nipple wasn't stripped either, just gunked up on the inside.
