Need Help figuring out what bell housing to get

Lakewood makes a bell housing
MOPAR SMALL BLOCK & GEN3 HEMI SWAP BELLHOUSING KIT; A833 4-Speed & TKX TKO 5-Spd | eBay

4.850 is the maximum bearing retainer size it will handle. Maybe have the retainer machined down?

Just a suggestion. I know the OD bell housings are not easy to find.
