63 avanti transmission seal

[dazavant]

Changing output shaft seal on the rear of my 63 (removal of this thing is another story entirely).  National seal number for this is 473234 (same as Auto Zone's #).  Here's the problem the National seal has an o/d of 2.502 vs my original 2.375.  Anybody have any insight on this, thanks.

It may help if we knew if you were referring to a 3-speed, 4-speed or automatic.  If it is an automatic or 3-speed, they are in SI's catalog for $10 and if it is a 4-speed they are in SI's catalog for $5.50..

Thanks for reply, it's an auto and I found one at NAPA.  National needs to correct their catalog as does Auto Zone.

Thanks again.
