I hav a bf mazda 323 .I changed my engine awhile ago from d orginal 1.5 engine to a b6 engine n Transmission .The b6 has a Transmission leak n needs rebuilding. Wanted to know the Transmission from the 1.5 engine is in perfect working order . I tried fiting it on the b6 engine but front housing is a bit smaller.Is there a way to line it up on the b6 to work with some modification...
