MrPerfectionest, if by uni-body, you mean the pressed steel piece of junk under most cars, I mentioned that in an earlier post. Please re-read. I stated the following:
I also know newer vehicles (I meant stuff post classics) do not have a frame per say but actualy are pressed steel.
I am, as most people do, using the word frame to generically refer to all chassis or support structure in a vehicle.
So please stop nit picking. It does not negate that my point is still valid: mounting to the frame, whether it be real or a pressed steel uni-body or the chassis (whatever you want to call it) is a better option than the body.
