When fitting the 3626-106 on a Cadillac application, confirm the driveshaft tube is 2.500" OD with 0.083" wall before welding. The threaded 12x1.75 bolt holes require M12 fasteners at 1.75mm pitch. The 18mm pilot diameter must be verified against the Cadillac companion flange bore. The 105MM bolt circle group includes the 3626-106 (THRD 12x1.75) and the 3626-105 (12MM clearance holes). Both share the same butt diameter and face-to-weld length, but the 3626-106 is the threaded-hole variant. Confirm whether the Cadillac companion flange accepts threaded studs or clearance bolts before selecting between these two units.
