NP440/A833 tranny install

[Chevystep]

Hey guys, I'm finally dropping the 82 Chevy truck OD tranny (3 speed + OD) in my 66 behind the 283. I have the iron case NP440/A833 and the original aluminum bell housing that fits both bolt patterns and it appears to bolt right up. BUT i don't have the dust cover for this bell housing or the starter. Starter appears to be easy, just buy an 80-85 or so truck starter. But does anyone know what dust cover will go on this aluminum bell housing? I reckon I can fab one, but if they are out there for another similar bell housing, I'd sure like to know! Also this bell housing has no mounts on it, but the tranny has a rubber one on the tailshaft end, so I guess I'll just hang another crossmember to support that tail mount. Think three points of support (motor mounts and tailshaft mount) are good enough?
