AG175 motor in a AG100 ?

[AG.02]

they are the same bottom end arent they? will the 175 motor just drop into the ag100 frame? thanks in advance:Punk:

I put a 1980 ish AG175 motor in to a mid 70s frame, everything fitted but the rear gearbox mount on the later motor was wider, I just cut the engine plate and re welded it in place
