I’m on the home stretch of my 2.8L->6.6L swap but I can’t find a slave cylinder bracket that works. I have the original 1988 clutch cylinders, the 400 is out of a 1979 C10, Summit’s 700170X bell housing, and I’m running the T5 until I can swap up. If anyone knows of a slave cylinder bracket that works it would be insanely appreciated.

Notice the fork is angled correctly for the third gen floorboard. And the fork ballstud is placed to work with an 84-92 V8 third gen slave, fork and throwout bearing travel.

Floorboard clearance led GM to angle the fork down on other bells including Monza, Vega, Monte Carlo, C4 Corvette, and 3rd and 4th gen F-bodies.

And the fork ballstud is located closer to center. So if you used all third gen stuff from pedals to slave, the fork wouldn't move enough at the throwout bearing to release the clutch.

So now you get to go aftermarket concentric slave cylinder.

Or go with the bolts-right-in option.
