There isn't a Hack-n-Tap in that pic.

 

look at pic #1. Notice how the bearing comes out from the housing just a touch? Id put my money on having the race fit in that groove. also does the seal have an opposite shaped insert that would fit? or would it sit flush with the groove?

 

That's what I figured. I came across the t-case drop and thought it was a possibility, but I already have a brand new hack n tap ready to go on, so it's all good!

Thanks
