yea, i understood! i didn't think the d-shaft was wearing 2 preppy button up sweaters...that's a really good tip, i can start trying to find those parts, b/c i so want to sas my tahoe...i looked at sweetk30's sas thread...and from what i could see the front spring mount goes under the front frame horns & b/c of the way the frame does on the ifs trucks, the rear shackle mount actually goes on the inside of the frame...i am searching and reading all the sas threads i can find...then I'm going to talk to kert about a bumper center w/rad support mounts & spring mount all integral that will fit right on the frame. i like his bumper center and when you add the spring mounts and rad support its just sexy & kills several birds w/1 stone.
