Small Block Bellhousing That Fits 4.8" 4 Speed Bearing Retainer

I used the 5.125 housing and had a ring fabbed by a local shop, to center the retainer, then dialed the housing, to center the hole to the crankshaft.Maybe not the cheapest, but now can use any tranny.
-The last new scattershield I installed for a customer, provided a PN for the ring. It might have been a Lakewood; dont recall.
