1. Bore out retainer dia. in bellhousing to match the trans., or alternately, turn the retainer down some, and then bore out the bellhousing.
2. Put the two together, use a suitable transfer punch to transfer the bellhousing holes to the front of the trans.
3. Drill and tap suitable holes(.5"x13) in front of trans., make the bottom holes blind or seal them up w/ epoxy, etc., so one doesn't get a bath when removing.
4. Bolt them together using bolts from the inside of the bellhousing, requires bellhousing to be removed, or through bottom access plate if so equipped.
5. Do your clutch/throwout bearing details.
