short answer, yes it can be done with the engine still in the body. what we ended up doing is cutting a foot out of one frame rail BUT make sure you deal with the same border guard, some will say that is all you need, some will say "no way". the customer contacted the border crossing he wanted to use, spoke to each of the guards at different times, found one that would accept the frame chunk removed, found out when he was working and schedualed his trip around the guards schedual.

went without a hitch BUT could go sideways so make sure you take ALL the precautions...
