This plate will convert the rear 3 finger output to a spicer 1350 flange (3-2-119). There has been talk about plates like this causing vibrations, but we are able to confirm during stringent recent tests on our 9500rpm balancer that this is not only NOT causing vibrations, but the pin that this centers on is a direct centerline to the differential and transmission. This part is precision machined to carry that centerline flawlessly. Recent testing on our machine also found yokes with u-bolts and straps to create vibrations (we tested 9 major brands, ever see a NASCAR ball to check runout ?) So if your putting a GTO rear in a hot rod this will make it an easy one...
This plate will fit (has dual patterns to fit all)
