1997 B4 Rear Suspension - Alignment

Has anyone ever had to shim their rear susp to get proper alignment specs? If so, where did you get the shim from?
All I've been able to find so far is an "EZ SHIM", and I'm really not interested in using a plastic shim back there.
Gotta correct a toe-out situation.....no doggie tracking wanted!

Yes, I had to shim mine years ago. I used the metal ones from NAPA and had my garage install them when doing an alignment. Do not get the plastic ones (or the magic plastic ring), they don't last, deform once you tighten everything down, and are destroyed if you need to adjust it slightly.
