Rotisserie Construction

[67drop]

So I've searched the threads for some info on body rotisseries and have decide to build one. For the rotation tube, some info has said to drill holes and use pins to lock the body in position, while others have bolts with welded nuts to pinch the inner tube. The later is an easier option for me but will this be enough? I would hate for the body to roll when i was next to/under it. I will be doing just the unibody assembly from my 1st gen maro. The front car mounting seems simple enough (subframe mounting holes), but where do I attach the rear? Any other advice or plan ideas for constuction on a rotisserie would also be appreciated.
