But in order to use the bigger retainer, you need to to get a tranny case with the larger bearing, so a trans rebuild is necessary (at least transferring internal parts, if they are all good).
So it sounds like the fix is to get a case, swap your tailshaft,etc. and machine your bellhousing for the larger retainer. I might look into doing that. This is assuming that there is no interference between the CF clutch weights and the Tilton TOB.
