    66 differential front yoke part #

    Can anyone tell me the original production part number and any service replacement part number for the front yoke (if that's the correct name) that the driveshalft U-joint connects to of the rear differential for a 66 small block?

    Thanks,

    Gary

    The original PRODUCTION and currrent SERVICE replacement part number for the pinion (companion) flange used for all 1966 Corvettes (as well as all 1967 Corvettes and all manual transmission 68-70 Corvettes) is GM #3878972. It's still available from GM for a current list price of $94.55.
