Nostalgia & History > SP ACF Stack cars FC-270-1 - photo request

Good day, I'm readying myself to build multiple sets of the 5-car stack sets built by ACF for SP. Here is a link to a couple of photos: https://www.trainorders.com/discussion/read.php?11,2647388,2647388#2647388

I've accumulated a number of reference photos over the years. However, I've yet to find a good photo of the floor. The article in October 1983 issue of Model Railroader has a partial photo which I can use, but I'm hoping someone may have a better photo(s) of the floor. I've also checked the SPH&TS Trainline #75 which unfortunately doesn't have any floor photos either. 

Any help would be greatly appreciated. 

Thanks in advance,
Rick
