As Home Brew points out, these are F-150 suspension systems. The one in the red pickup is from a '78 and the one in the roadster is an '81. I'm also currently putting together another chassis which will have the beams from a '79.
Personally, I don't think the Ranger beams are really appropriate. They are shorter than the F-150 beams and they are quite "modern" in appearance. I also don't use F-150 beams made after 1981 because they changed the style and they no longer have the drop forged traditional look.
