THIS IS A MECHANICAL BRAKE AND CLUTCH SET UP WITH MOUNT BRACKET. THIS IS NOT THE HYDRAULIC SET!! IN ABOUT 86 THEY STARTED USING A HYDRAULIC Z BAR. THIS WILL REPLACE THAT IF YOU SO CHOOSE. THESE SHOULD FIT 73-91 SQUAREBODY TRUCKS. THIS NEEDS TO BE CLEANED UP, BLASTED, PAINTED ETC. IT MIGHT NEED NYLON BUSHINGS WHILE APART. SOLD AS IS. I’m including the clutch rod but the ends will need repair. There is also one end for the return spring That is missing. Otherwise these function well.
