Master and slave retrofit

In my 4th gen I used to have the POS T5, now I'm soon to be installing my Super T10 and I'd like to keep the existing master and slave setup. I know I'll need a bracket to mount it all, but plainly, will it work on a linkage type setup? The hydraulic stuff is quite new and I can't afford to buy and fit a 2nd gen linkage. Suggestions?

Can't see why not... the dimensions of everything on the front of the transmission are the same.

Since you obviously have a 6-cyl car, the biggest problem you'll have to overcome, is if whatever V8 BH you end up using rotates the trans like a 3rd gen one does (your 6-cyl one won't bolt to a V8 block). A T-10 doesn't have the funky trans mount boss for that. If you have to mount the trans straight up, you'll probably need to fabricate a bracket for the slave that would bolt under a couple of BH bolts and/or trans bolts.

The next issues will be a shifter; and of course, a torque arm mount. I can't help you with details as I know absolutely nothing whatsoever about 6-cyl cars, except that they exist.

I'm using a '74 Vette aluminum bell and the 3.4L was pulled in favor of my 355. Tq arm was removed alltogether, replaced with a 4 bar/link.

I don't even know if the slave is a push or pull type, but I never thought about using a bolt hole for a boss mounting point. How much stress would a slave have to endure (ie: pushing/pulling forces)? I'm using a Zoom HD replacement 11" clutch, and the shifter I can make if need be.

Now, if it worked, would it last for any length of time?

Well I don't know how much force it will have to endure, exactly; but the factory bolts it in with 2 bolts with 10mm heads, so they're what, 8mm bolts max? and it pushes on a piece of sheet metal (the fork), so it can't be all that much.

I'd try building a bracket to duplicate the placement of the slave cyl, with the bracket bolting under the bottom 2 BH bolts. A slightly reinforced L bracket ought to do the trick, maybe some ¼" thick steel about 3" wide bent into the L shape and a couple of gussets in the corners. Maybe an additional piece to go back to one of the trans bolts, to triangulate its support.

If it's the factory T-5 hydraulics, I believe those push, just like a linkage type would. So it ought to work. All you'd really have to do is to make sure the fork got moved far enough to release the clutch; the slave moves about 5/8", so you'd just have to make sure that 5/8" on the end of your fork was enough to actuate the clutch properly. I don't know offhand how much motion that takes, or what the factory fork ratio is, or anything like that, so you'll have to measure it I guess.

Again, I can't see why you couldn't fairly easily make something that would last hundreds of thousands of miles. It shouldn't be too hard to do.
