There is no way I can burn the existing rusted bolts off without professional help (in more ways than one, ha!)

Any tricks you all could share?

Try a welding shop. They can cut off the old bolts in about 2 mins and they usually could care less about what you're doing to your car or why.

Everything after that is a fairly easy DIY.
