915 will look like 915/XX on the bottom of the case. Not sure how or where the 901 is stamped. It most likely will begin with 901 though. If you're interested in a 915, look for a later version as these are all aluminum cases (after '78), stronger R&P 8:31 (3.88) and the early boxes didn't shift as well as the later boxes. If you can find a factory LSD box even better. 915 was installed from '72-'84. 901 was '65-'71 (I believe on the 901). Also 915 has a conventional H pattern and the 901 has a dogleg 1st. A Bentley manual should tell you the "XX" designations as far as years.
