I was taking off my drag radials and noticed this

 

4gen disease, many also

 

The stockers, at least the ones on my 94 appear to be some sort of rigid "foam". not a hard rubber. Not sure what they are made of, but is obviously doesn't last 20 years. I need to look at mine... haven't driven the car in years.

 

Fixed it. Even got new bolts from the Chevrolet dealership just because that’s how sick I really am.

 

Where did you purchase them?

 

I just got them from Summit Racing

 

Strano sells those, for $63. He also has “his own” urethane for $25. But he does note that the red urethane are the Jeep part that a lot of people buy.

 

If I would’ve known I would’ve bought them from Strano. Reason I didn’t want to buy the cheap Jeep ones is I didn’t want to cut the lip of the car off or some people make/add spacers.
I just wanted the GM OE bolt in ones.

 

I think the GM ones are fairly new product. Look better than the Jeep stuff.

I had to cut off the projecting edge of the original factory brackets to prevent my 17x11 ZR1/GS replicas from catching the inside edge of the wheel rim when jacking the car.
