Bells are made on the tranny. Amc spirit, concord, some postal jeeps 2 wheel drive, etc. early to mid 80's with a 2.5 then have the 904 built. No different than all the Chinese 451's and other mopar builds and swaps. Keep it mopar..... Yea,lol. Most built mopars out there are 1/4 or more Chinese. LS and mopar,,, good swap imo.
