I have not seen the "new" complete floorboards installed at this time, but I do have knowledge of the "one piece left and one piece right" combination floor/toe pieces from Taiwan........don't buy them if you want to retain the original look. They fit poorly and they do not have the seam that you would have if you had two pieces as original. They do not include the additional raised supports for the brake, clutch and gas pedal. They don't have the proper holes necessary to install the e-brake pedal and other misc holes required for original installations. They are designed to fit all trucks/suburbans/panels etc. If you just want a simple quick fix, they might work for you. I have a set and my floors and toeboard are also in need of repair. That's my summer project. I was disapointed to see the poor fit of these panels. I have not decided which way I will go now.
From what I have heard about the one piece firewall that includes the toeboard panel, it's pretty close to original specs, but the owner has not installed it at this time. If you choose to install the one piece truck floorboard, be aware that it is different in the suburban at the seat riser, you will have to do some sheet metal fabrication to make it work in your suburban because of the two piece seat arrangement.
