New, need suggestion

[Banjo]

I just bought a '66 SWB fleet w/stock 283 and turbo 350. I will be needing to do floor and rocker repairs and bed rebuilding (no wood left) and wanted to ask "those in the know" what sources should I contact to obtain catalogs for parts? I have no clue who would be my best balance between quality and pricing? I'd kinda like to consider a full floorpan, as my tunnel has been butchered too, but I'm not finding that on the internet, though I'm sure it's out there.
I have been lurking a week or two and am very impressed with the gracious attitudes I see on here and helpful knowledge, I've viewed some other forums for differing things and have noted quite the contrary. I thank you in advance for advice regarding suppliers/vendors and apologize if I missed a nice thread with that info already contained. Banjo.
