Default Upper Rear Spring Isolators

I'm replacing my rear springs (light sagging and since I'm replacing the shocks anyways). I figure since I have access to it, I'd rather change out the spring isolators. Prombles is, I can't find anyone who sells these. Of course, my isolators might be in good shape, but I'd rather have new ones.

GM #10290379. I doubt if yours will need replacing, never seen a deteriorated one. But if you must, search google images, seems many available on ebay.

I actually found one isolator at a Chevy dealer in McAllen TX. They wanted $54 for it and they only had one. Its still there if anyone needs it.

Lots of guys (like me) have them laying around from doing the heater hose mod. Like FirstYr said, I've never seen one deteriorated.

I've had them out/inspected 3 times now, approaching 190,000 miles.never found any cutting,hardening,deterioration. I also got a set from a friends' SS with about 10,000 miles on them. No difference in quality between the 2 sets.

There's a guy on here who also used isolator from I think a cobra mustang? Terminator mustang maybe? Said they were just a tad bit thinner, but fit in the seats and springs perfectly. You'll have to search around for the thread, he has a part number listed in it. His reasoning I think was that he lowered it just a tad but thought the hose mod was ghetto.
