I have a 1975 2002 that unfortunately is the automatic transmission. It is otherwise rust free, working AC, great interior, sport seats, etc etc etc. I would like to swap in my 1988 325is M20 and Getrag 260 transmission. I figured if I am doing a tranny swap I might as well keep the engine connected to it. I have searched and searched for posts about how much larger the tunnel is on the auto cars vs the 4 speed. If there was a thread I missed please point me in that direction. Here is my question:
From what I have read the 260 is too big in the bell housing area. Due to the larger tunnel (especially near the firewall based on my searches) will the 260 fit without hacking away? I have a 245 M20 bell housing but no trans yet. I am trying to find out if I need to find a 245 or put the $$ towards keeping my 260. I know the 265 is taller and wider which requires more tunnel mods. From the pictures I have been able to find it looks like the 260 is smaller, but is it small enough.......
Any help ESPECIALLY pictures would be greatly appreciated.
