Panhard bushing

[el curioso]

I need to replace a the bushing from the track bar (pan hard bar) where have you all bought them from or do bushings from other applications fit? Allready took the bar to the local common places but the idiot behind the counter asked me if the truck had a\c, engine size and I knew from that moment he wasn't going to look and see what would fit other than what was on the screen. Then he tells me to look for it on the web cuz he didnt know that GM even made this type of suspension!

sorry had to off load some where

Thanks in advance.
