I just saw one made out of an old Honda 250 'Big Red' three wheeler, and a CB750 engine installed in it.. I bet it is unreal lol... I know that's not what you are building, but it was pretty cool.

Do you not have an engine cradle or frame of you do measure that, and build accordingly.
 Remember it would just slide in.
Easiest to just buy an arm and cut the front off, stay way from later plastic bushing ones.
