I just purchased an SYE kit from jb conversions and was wondering when I am putting it in and run into trouble if there was someone who has done the install on the 241 case I could turn to. needed to get the kit so i could run wood's cv driveshaft. With my blazer being at 8" susp. the vibrations were horrible. you see I bought the truck like that being very ignorant to the scene and realizing that I and the person who owned it before made a mistake with 8" of suspention lift on a short wheel base. When i bought it there were only 2.5 degree of shim in the back which made for some U-joint breaking key rattling vibrations. I currantly have 2 six degree shims for a total of 12 degrees in there now which turned out to be too much but will be perfect for the cv shaft. I know i should get the perches rewelded but with a 14 bolt on the way and lacking skills to weld I just have to go with rediculous shimming.
