ok, i finally was able to get around to going to the john deere
place. They had a nice shelf full of shims, but none the right
size. I settled on two that are way too thick and too small ID..
they were .50 each, so i figured it would be better to try to make
them work instead of having nothing to try..
fortunately, the ID is only about .010 smaller, so i shouldn't have to
spend too much time hogging it out..
i went to NAPA and I bet if they really knew their stuff, they might
have pulled out a book and found the parts, but they were so damned
sure that they wouldn't be able to get something like this, they
didn't *NEED* to pull out the book.
I didn't even bother with anywhere else.. lol
