Rear End Question

Hey guys!

I bought a new truck tonight for it's decent body and good exhaust, but I need to know how I can tell if the rear is Posi or not... Its a 14 bolt in a 74 3/4 ton truck, only reason why I suspect is it a Posi is how it reacted when the PO was backing it up through the dirt as we was turning, the one tire on my side was grabbing the dirt a bunch...

The truck has a poor tranny in it, so I couldn't find out via the good ol' patch test :P

Nope, I found a local truck just down the road. Has a straight bed with only surface rust, and comes with two front fenders that are in extremely good shape, new front bumper, new front valence, a fairly new suspension, very heavy duty hitch, and is in fairly reasonable condition otherwise. I plan to combine the two trucks into one nice truck, and sell the other resulting truck. Paid 1500 for it, probally can get 1200 for the resultant truck, so I felt it was a decent deal

Well, I've got one of those already, not a chance you would wreck one in good shape, but my current 14 bolt's pinion is nearly done for...
