Hey guys/gals, I am new to the board(1st post) I know nothing about subaru and lack ever having the joy of owning one. I was just curious to know if the subaru 4speed manual tranny had a removeable bell housing and tail housing. I don't really care what type of subaru, just if they made any at all. Also, if they did, does anybody know the length and width of the tranny's gear box?
