The 8 1/4 thread

The sure grip carrier fit right in, but there was no way to set the gears up, they was to fare out to be shimed to match up .

Even the side rings that kind of have threads would not take up the slack.

So the gear fit in the unit but just seems to narrow ?? I misunderstood you I guess cause I thought the ring gear would not fit the carrier at all
