I have that combination on the truck which I am building. The GMC crossmember sits 1 1/2" lower than the Chevrolet crossmember. I made a 1 1/2'" spacer to account for this.
I don't believe so...everything was good 12 years ago when I took it apart, all the same parts. Should I try dropping the rear of the fenders?
