Hello all,

I've got an 8 3/4 rear axle out of a 73 D-200 truck. I'm going to install it into an 80 D150. The current axle is an 8 3/4 489 case unit, open rear. I'm going to go junkyarding and see if I can find a center section with the clutch type SG in it already. Rebuild that unit and put in my axle. Which code should I look for to save crawling under cars/trucks in the junkyard ? I did take a look in the tech section and didn't find anything on it.

Thanks.
