i bought a set up on ebay to convert my 350TH to a 4 speed in my 66 lemans. i think you could probably buy all the parts you need out of catalogs but i think that would get pretty expensive. a couple of things to remeber.. i had to remove the drivers side front fender so i could weld the little bracket to the frame for the z-bar and i had to do some floorboard modifications for the shifter and firewall modifications for the clutch linkage. the original crossmember and the drive shaft didnt need any mods. also, if you are running headers you will probably find that the clutch z bar will hit it. alot of headers claim that they will work on 4 speeds but the only one i could find that would work were the hooker super comps. hope that helps, you can e mail me direct for more details of you like.

and yes, it was worth all the trouble to be able to bang through the gears with a 4 speed.
