James G. Posted July 13, 2012 Share Posted July 13, 2012 Hello everyone. I am looking to swap out my 2.56 open gear, stock 8.5" 10 bolt rear end for a 3.42 - 3.73 geared rear end and have a "fit" question. I have a guy willing to sell me his 8.5" 10-bolt rear end with 3.73 gears, used, which came out of a 1984 Chevy 1/2 ton 2WD pickup. I can get it at a very good price, with brand new brakes to boot. My question is, will this bolt up to my 1972 Monte? I have a 8.5" 10 bolt factory rear end in it now and was looking for something that I could pretty much bolt in and go. Thoughts? Thanks in advance for the help. Quote Link to comment Share on other sites More sharing options...
71monteme Posted July 13, 2012 Share Posted July 13, 2012 James. the rear end on the truck might have a different shock mounting points. usally one in the front and one in the back. also most truck rear ends are leaf springs not coil. by the time you cut/weld put new perch on that rear end, might be cheaper to put in new gears and a posi in your old one. thanh Quote Link to comment Share on other sites More sharing options...
