Wanted to confirm some information on the 8 1/4 rear end (carrier swap)!

I emailed Doctor Diff asking about the housings. Cass Eslick confirmed via email that there is only ONE HOUSING for the 8.25" differential.
If you are saying only one housing for dodge/mopar I need to learn about loading different bearing I guess, the low gear sets I tried in my 73 duster 8 1/4 hit the housing... hmmm.
