Rear bumper question

[ChaseDale3and8]

I was at the O'Reilly by my house today buying brake pads for my wife's Durango. The manager there noticed that I was driving my old 86. He told me that he's currently parting out an '85 K5 Blazer and asked if I needed bumpers for my truck. I told him that I have a front still new in the box that I haven't put on yet, that I have been saving it until I tear this truck down to the frame.

He said the bumpers on the 85 Blazer that he has are in excellent condition and that since I work with his mom he'd take $100 for the pair. He said he even has the tow hooks, which I have been searching forever for a set.

My question is this. Will the rear bumper brackets bolt directly on to my truck? Are the bumpers and the brackets the same, or are they different? If so, can they be made to work? $100 for a pair of bumpers that I could bolt on and use right now is a deal that I can't pass up as long as they will fit, so I wanted to ask you guys if any of you have swapped a rear bumper off of a Blazer onto a pickup. Thanks for replys. ...Joe
