IMHO your better off going with the "Keisler", now SST (Silver Sport Transmissions) pedals, I wouldn't waste the time or money with a 833 4 spd, put a TKO 600 or T56 6 speed if your going to the trouble of outfitting a C body, you could go with SST's hydraulic throwout bearing, eliminating the linkage nightmare, and you could drill out the SST brake pedals to fit your linkage bellcrank for the power brakes I assume you have, I'd run a factory style B/C body floor console, I'd order the TKO/T56 with a 68-70 B body shift location so that I could use either the 69 B body 4 spd style handle, or if you like the 70 console pistol grip, SST has all the handles as well, you'd just have to source a console...if your car is bench seat, you could do the B body benchseat shifter 69 or 70 pistol grip style as well
