How about the rear yoke on the rear driveshaft. The part that bolts to the rearend?

Also whereabouts are you located?

Thanks,

Heck, since I'm currently running two diesels vehicles (car and truck), I've switched everything on the place to 15w-40 Rotella, Motorcycle, 4 wheeler, lawn mower, you name it. Sure makes it easier not having to stock a bunch of different oils.

Don't know why I didn't think of this earlier. I ran outside and snapped a pic of the driveshaft piece Dad needs off the other M37 he owns. Which is convienently parked in my driveway. Here's the Yoke he's after. The piece in the red circle that's bolted to the end of the pinion on the rearend. http...

Here's a pic of it for you. If I had a pic of the broken driveshaft piece, I'd put that up as well. This is the day it was bought, back in August of 06.
