THANKS I forgot about the closed drive shaft the truck im trying to put the 1.5 ton parking brake in is a 1 ton with open drive shaft but has linkage and cables and I just liked the simpler version of the big bolts My truck has a 1958 235 6 cyl. with the sm420 so I guess the Trans. is interchangible just not sure if the brake parts are seems like some one has tried if not Ill see what i can do and post for others
