Tons Posted October 10, 2009 Share Posted October 10, 2009 A friend of mine recently bought a 68 Buick Skylark that he is going to part out, He said I could have the posi rear end from it. I was curious if it will fit my 72 Monte. bolth rear ends look the same as bolth cars are GM A bodies. Quote Link to comment Share on other sites More sharing options...
Sam (Bones) Posted October 10, 2009 Share Posted October 10, 2009 you might have u-joint issues, other than that, it should bolt in Quote Link to comment Share on other sites More sharing options...
bobsmc Posted October 11, 2009 Share Posted October 11, 2009 you will have to use a combination ujoint like bones said. my 71 has an olds 12 bolt posi in it and had joint issues. spicer makes a comb joint that will fix u right up! Quote Link to comment Share on other sites More sharing options...
Guest slacker Posted October 11, 2009 Share Posted October 11, 2009 Ditto! What they said.. I had to use a Splicer in a Chevelle. Worked out great.. Quote Link to comment Share on other sites More sharing options...

Guest silent72 Posted November 5, 2009 Share Posted November 5, 2009 im thinking of getting a 10 bolt 8.5 from a skylark, am i gonna need the combination u-joint? i think the rear end im takin out on mine might be the 10 bolt 8.2. will i need a shorter or longer driveshaft?

monzaz Posted November 10, 2009 Share Posted November 10, 2009 If you are going TO a 8.5 from any other GM rear you will have to shorten the drive shaft about 3/4" ...But best to mount the rear and then measure and cut after fully installed. You will nee the combo u-joint. If you had a BIG BLOCK with the large rear end yoke in a 12 bolt you will be fine. Jim Quote Link to comment Share on other sites More sharing options...
