B1800 to a B2000-B2200 ?'s

So this has to do with my 75' Courier, The truck is already running a Mazda B-Series from the factory with a 5 speed. So I was wondering if the B1800 has the same motor mounts as the B2000-B2200? If so do you guys think the newer B-Series may drop right in?
Thanks LeDevil

You referring to the pre 84 style or 86-93. If your referring to the 86-93, no they are not the same. The only thing we can interchange with those years are literally wheels. Even that the whole offset and backspacing is still a mystery for us.

Well that sucks I was kinda hoping that the motors would swap straight over Thanks for the info

your up late
