Am in a dilemma with 1953 Suburban body mounting blocks. Am 99% sure the Suburban is 100% orig.** When I removed the body for body and paint work all four mounting blocks measured 1&5/8" in height but the kit I have from Jim Carter all four blocks are 2&1/4" in height?? Should I mfg. blocks like the orig. one's or go with Jim Carters kit?? All thoughts appreciated.
