Sorry I've been gone so long, gang! Here's an update... I had the truck in my uncle's body shop for over a year while I went through a divorce, a heart attack and a bunch of other crap - but all along, I've been dabbling with the truck. Well, it is getting really close to being done. I put in the T-56, and the shifter comes up just about perfectly, right between the front corners of the '05 Silverado high-back buckets where my hand falls naturally on the knob. All is sweet .... except the blasted clutch. I put a lot of effort into figuring out the correct flywheel, clutch, pressure plate and TO bearing to go with the T-56 (Be advised - if any of y'all are considering this swap, if you are accumulating parts piecemeal like I did, here are helluva lot of folks out there who don't know their tails from apple butter! LOL) I finally gave up trying to figure out which high perf stuff would work best and opted for all stock OEM stuff to fit the '94 Z-28 with a T-56, including a stock '94 Z-28 hydraulic clutch master and slave, which I bought in a sealed set... no problem. Just have to figure out how to rig it to the firewall. But Uncle didn't want to try to adapt the master to the firewall, so he took off the slave, discarded the master and line I just bought, and used an old, original brake master for a clutch master. So far, probably still ok, right? And it solves the pedal hook-up issue. But now down where the slave hooks up to the T-56, apparently there is some sort of spacer missing where the slave mounts up, so he cobbled up this nightmare adapter to mount the slave, and apparently there is something off somewhere, as when you push in the clutch, the pedal does down about 3/4 of the way to the floor before the clutch disengages - and 1/2"-3/4" further on the pedal and it sounds like the yoke is into the danged pressure plate! SO... does anyone out there have any idea what in blazes would cause this? And does anyone have any idea how thick this missing spacer is, or better yet, the part number for it? Thanks for your help, everyone!
