hi guy .im doing a 66 gmc/chevy crew cab to a 86 chevy crew cab single wheel ,frame ,and was told the 66 truck will not fit the 73 and newer chassis -due to the kick ups front and rear? my 66 crewie chassis was a piece of junk when stretched and some previous owners really screwed it up !i have seen in c the "classis trucks " magazine a green and white 65 crew cab truck that was mounted on a 78 ? chassis ! it was located in the tucson ariz. area ? if i could find the owner to verify what was used it would be great ! any way let us know if you get body to chassis w/ some pics ?thanks mike "carryallman" wahl norwalk iowa
