Motorcycle Repair: frames, evo motor, best bet

Question
72 harley big twin frame will be converting it over to a ridgid frame I have an evo motor any hints on how to get it to fit.

Answer
I have not done this type of conversion before, however the mounts shouldnt be all that much different, best bet is to try and find one in a bone yard and measure the distance between the mounts and go from there... Sorry i dont have more info for you..
