a lower patch??? get some 18 ga sheetmetal ( from a real steel co) for $5 and fab your own. if not,,,, buy the cheapest patch, and cut and make it work.
I was reading not long ago where guys bodyman was trying to use AMD full quarter on a B body, forgot what model. supposedly stamped on Mopar old dye,( in China no doubt!?????),,,,
but a bodyline was of 1/2 inch, the guy had to split it, fill it to make it work!!!
sorry, but if I had paid that $$$ for the quarter, shipping, then have to pay the body guy to make it RIGHT, I would have pooped in my drawers!!!!! or if I had to do the work at least did a lot of cussing!?????
