I am currently redoing an Ohio burb, Have fun
I am lucky enough that I have another burb to use for the inner braces, wheel tubs, ect...
As far as the patch panels go...
Your best bet would be to order the burb lower patches & the rockers. Keep in mind that the pass side P/U rocker is different than the pass side front door rocker. You will need to modify the p/u rocker to work but it can be done.
For the wheel arch, while not the cheapest way to do it, you will need a pair of SWB bedsides. The SWB bedsides have the correct bead in the lip as well as the correct shape at the leading edge of the arch(more squared off). The LWB bedsides are shaped somewhat different at the leading edge of the arch(more rounded). The pass side swb bedside can be used to go into the doorjamb and to the rocker but you will need to make a "pichweld" for the bottom. The drivers side you will need to have the lower panel from the wheel well to behind the front door fabricated.
