question about floor repair panels.

I don't have cable where I live, and haven't seen the show since this project car began, but caught it this morning, and am quite interested. I've previously restored a 1980 elcy ss with the 4 speed, and I also own and am planning on redoing my 78 malibu also originally with a 4 speed, and I'm in dire need of repair floor pans as mine are currently patched, but not pretty.. To the best of my knowledge, goodmark ind. doesn't sell the patch panals, and nowhere on your site here do you show where your getting, or have gotten your floor pans from. So where are you getting them from???? and do they make replacement panels for the malibu?? Another question I have is what brand, and part number front springs are being used, and will the big block clear the air conditioning?? Any help would be greatly appreciated.
