Recently acquired what I believe to be a JDM ITR tranny.
4th gear 29 Main and 30 on counter. 5th has 33 on main and 26 on the counter.
My question is it possible for LS or differential bearings (17 in illustration) to be installed on ITR differential? Just trying to be sure bearing installed on tranny is correct since this is used item.

The the bearing visible from the top side is NTN which it appears makes the Honda part 91005-P80-E31, the part number on bearing installed in mine though is TMB208CZ. This TMB208CZ part no. cross references to 91005PS1003 which is a Civic Del Sol bearing.
IT seems odd that a civic differential bearing would fit on a ITR differential, has anyone heard of this?

Also 17 is both a taper bearing and ball bearing, anyone know reason for this?



Part 17.
