Repo floor pan, cab support quality

[HeavyD]

Hi. The huge holes in my floor are really starting to get annoying, so I think I am going to have the floorpans, rockers, cab corners, and cab supports replaced soon. Has anyone had any luck with using repo pans, cab supports and cab corners? Do the lines on the floor line up Ok? I am going to buy GM rockers, but do the repo cab supports and corners fit well? The driver side floor (gas pedal area) has a hole big enough that my foot can go through if there is not a thick rubber mat there for support...will the new pans be OK or should I look for another cab? I really want the repaired areas to look good and not be obvious from 50 ft.
BTW, I haven't checked for cowl rust yet..will do that tomorrow.

Thanks!
