I'm afraid you aren't going to be able to buy them over the counter anywhere. Parts for the 3/4 ton 3600 rear ends are few and far between. The number of 3600's vs 3100's was a much smaller production run so reproduction manufactures simply won't tool up and make parts. I took mine to a brake shop that would still re-line them. If you have yours that would probably be the best bet.
