Transfer Case Repair -- Done

So the transfer case debacle is done and my Bronco is up and running again.

The main lessons learned was the '89 BW1356 isn't 100% compatible with '88 due to flange change and rear output shaft diameter change.

Parts costs were:
1. Salvaged '89 BW1356: $266
2. Driveshaft modification:  $300
3. Replacement transfer case seal (one looked bad): $25
4. ATF fluid (2 quarts for transfer case): $13

Total: $604.

For the cost it might have been cheaper to rebuild the old case or not; I'll do a post on that eventually.  But I do have a backup transfer case so that is a plus.
