At the recommendation of chryco I went with McLeod pressure plate (long 3 finger) and clutch disk...I also went with the larger 10.95(I think was the size).
I also replaced all linkage and rods, z bar, shift mech, lower clutch cover, input& throughout bearing...through Mopar(fork&adjuster), Brewers, Lordco
Mine is a 73 340, feel free to ask further. Ill help as best I can remember!
