When fitting the 3626-110 on a Pontiac GTO, confirm the driveshaft tube is 2.500" OD with 0.083" wall before welding. The 12MM clearance bolt holes and 32mm pilot diameter must be verified against the GTO differential companion flange — the 32mm pilot is a key feature distinguishing this clearance-hole variant from the threaded variants in the 1100MM bolt circle group. All three 1100MM bolt circle variants (3626-110, 3626-111, 3626-112) share the same 2.344" butt diameter and 1.625" face-to-weld length. The 3626-110 uses 12MM clearance holes versus the threaded options in the -111 and -112. Confirm whether the Pontiac GTO companion flange requires clearance or threaded bolt holes before ordering.
