Damn! They should have some!
FWIW the T1 and T4 shims are the same.
If there are any VW junkyards or motor shops near by they can help out for sure.
I have some if you are really stuck in a bind, but I would just need to know what thickness you need to get the right shim stack for you. On a T4 you need 2 shims, T1 gets 3.
... It is better done locally as getting the right endplay takes time. I just did one on a T1 1600 two days ago and literally had to test fit it 8 times to get it where I liked it. No something that just slaps together
Good luck,
