Any suggestions??
I would be surprised if Chevy went through the trouble to eliminate the hole that is in every C3 for the 1982 swan song model.

crawl into your foot well with a flashlight and see if there is a round precut circle with a plug. I am guessing it would be around "10 oclock" in relation to the steering column




This is on my automatic 1981.

Pull the plug and you will (should) see a hole through the metal firewall. The fiberglass "skin" firewall will need to be drilled, but once you have located the factory firewall hole, you just need to drill from the driver footwell out.

this picture is the pilot hole on mine from the inside out, but now looking at the firewall (column, booster and master cylinder removed)



Here, with the steering column reinstalled, but still without the brake booster and master cylinder is the (a) stock clutch rod in relation through the factory 'hidden' hole



this is what a stock 80/81 trans cross member looks like. exhaust pipe(s) would pass under the passenger side (on the left in this picture)




and looking from the ground up with the 4 speed now mounted to the 80/81 automatic/stick crossmember...

OK. Keisler makes a hydraulic clutch conversion kit. I have the master cylinder kit on the way and will post when I get that. They seemed to know what they were talking about and knew the 82 was unique.
I also got a 79 crossmember for the dual exhaust. The thru bolt holes on the chassis and the ones in the crossmember are about 3/8 inch off-the crossmember holes are too low. Also, the park brake cable roller hits the floor and is at a different angle. Am I just stupid or does anyone else know of an easier solution than just making it work???

I found out the 81-81 crossmember is unique and no other will fit the chassis. Bow Tie Overdrives makes a crossmember of 1 1/2" tubing that will clear almost any exhaust configuration and is actually higher than the floor pan. I ordered one this morning. They don't make one for anything but 700R-4 and 200-4R trannys, but they sold me one uncoated so I can modify it for the Muncie.
Now for the driver's seat floor pan

I have another item that has yet to be mentioned... you will need the cross shaft assembly for the clutch pedal and the mount welded to the frame after you locate the tranny position.

I have hydraulic clutch so no Zbar or other linkage, just master cylinder and hydraulic throw out bearing. Zbar might be easier, but I hear the hydraulic is smoother and quieter in operation.
Thanks for the thought, tho.
