I have an 86 S10 rear end in my Monza. Im not sure what backspacing will work. It has 15" Bart (stock car) wheels on it. Do you see any issues I may encounter with this product?

Most likely this kit will work for you. Clearance to the frame/body of the vehicle or the spring/control arm mounts would be your biggest concern. The brake hats in this kit have 1.59" of offset. You would be best off holding a caliper in place and checking for clearance. Then order the kit with the appropriate offset brake hat.
