ohh did not know that cool
are the drive shaft flanges the same distance appart as the 7inch? if thats the case then game on!
Edit: just did a search on sierra owners forum....
"2wd diff top mount is 7.5 inch, 4x4 is 7 inch..... you can lop the difference off of the diff casing or cut and re-weld one of the mounting tags on the beam. As you look at back of the car it's top right hand mount you need to mod.
2wd saph arms are same as 4x4 arms so you're fine there...only ones that are different are 3dr arms (arb mount in diff place).
