`I need to replace the lower control arm bump stops on the 85 P32 Regal. According to Workhorse and Chevrolet, the original part number is/was 15631321 but it has been 'discontinued'. Starting in 1990,(according to Workhorse) the part number changed to 14054761. But no one can tell me if they're the same. I can get the 14054761 but have been unable to find the 15631321. I must get these since the front end is sagging 2 to 3 inches and will be replacing the springs, etc. Without the right bump stops, I'm sort of dead in the water. Would appreciate any help. If anyone could take the time to look at their 85 p32 chassis, maybe take a picture of their bump stops, maybe at least I can get an idea of what I should have. The existing one on the drivers side is all of 1" high. The existing one on the passenger side is almost 3" high, so it's pretty clear that something is amiss.

Henderson, the folks that make Super Steer products, have, on their own, ordered a set of bumpers from Workhorse using the new part number, and will see if they will fit the older P32 chassis. I'll let you know when I here from them. When was the last time you heard of service like that? These folks are really good.
