My case is similar to Mark's - I know I have several sets of all the
seals for TR6 diff's out in the garage... or is it in the basement - or
is it both? At any rate - I will take a look tonite.
I'd like to offer the following: I have purchased all these seals from
the local NAPA dealer on several occasions, and the parts that I got from
them were first quality parts... in fact I got my first neoprene type
seal for the pinion flange seal from them. As I'm sure you're aware - the
original on the older type diffs were _leather_.
So check with those folks as a source.
