Hope this is what you need.
Just bought these from AS in June.
I tried a couple parts stores this spring to no avail. However, I don't think I tried NAPA. Best of luck.
I paid $31.80 each.
Also, Gabriel no longer makes these shocks with a two piece rubber bushing.
They will not clear the top spindel to frame distance without some creative thinking.
Talked to airstream service and they have a large bar and just bend the spindels. Just what you would expect. Instead of calling Gabriel and telling them to change back, just bend the hell out of the spindel.
I am going to press out the rubber bushings, cut them in two pieces and install my new shocks.
