I'm getting ready to put a s-10 rearend in my 37 1/2 ton with a 4 link suspenction and coilovers. It looks a little narrow but should fit. The 4 link is a TCI for a 37 car (they don't make one for the truck)and needs modified becouse the frames are different. I'm a maintance supervisor so I have access to my machine shop at work, that will help! Has anyone put this combo in? Any info would help.
