i got a 79 blazer and finally got a 3/4 ton rear end .its out of ... i think it was a 76 i know how to measure it and everything for back spacing. but i heard that it is wider than the 10 bolt. the tires are 13.5 wide and the rim is 11 in. they are a agriculture tire and wheel iam going to take the centers out and put the 8 lug pattern in them. i have about 6 in of lift. so what do you guys think on the back spaceing? kind of w. ant the even look you know so that the rear follows the front.after reading this it sounds like iam talking in circles, but i know you gus know what iam tring to say.
