My local you-pull-it doesn't care - they go by part description. I told them they had a fairly rare (in this area) 21 spline np242 case and they said "well pull it yourself, we'll charge you the same thing, you go sell it on ebay." I buy enough stuff from them that they charge me 100 for axles even though they're list price 130, though it comes to 130 if I can't find my hydro jack and end up paying 20 to have the car put on a stand for disassembly and need to borrow a dolly to get it out of the yard (I hate moving, all my fun stuff is buried in storage.)
Think I'll take a walk through the yard tomorrow morning...
