Does anyone know if this is something I can pick up at the dealership? Or do I have a better chance of finding something somewhere else?

If so any ideas?

Gene...you looking for the "pin" that is welded into the frame that goes through the shock eye??

Yes that's the one Dan...

I was putting my Alcan spring packs on yesterday and I removed the shocks (just to get them outta the way) and it snapped on me.

Foothilloffroad.com has all that stuff.

I just placed an order with them; they were nice folks to deal with and everything showed up fast.

I can speak for them as well...I got my shock pins from them when I relocated my upper rear shock mounts....

In fact, I actually have two spare pins sitting at home if you want them Gene...I "believe" they will work...Not 100% sure as I didn't end up using them in what I ended up doing...I just can't remember if they fit the Bilstein 5100's that you would have or the 7100's that I have--two different eye sizes...believe the 5100's are 1/2" eyes and the 7100's are 3/8"...

Yeah Dan it's a 1/2" diameter.
