The above post is the reason God invented plasma cutters.
Sometimes, it's easier to remove things that are in your way. It's not hard to take the seat back area out. Then you have access to the wheel wells, and the shock mts. Make sure you jot down some measurements before you start, and put everything back to same. A lot of times I'll blow the spots out with the plasma cutter, then back the hole with a copper block when welding on the new piece.
To bad you're so far away Chuck. We'd be glad to help you out.
