Need help identifying cross sills

Trying to identify extra parts, so as to advertise correctly, yet I own 1955 and 1971 trucks. These appear to be similar to a post by 68is4me back in 2018. They are 49 1/2 inches long, and the two with riser "pads" measure 31 3/4 inches from center to center of the "pads". Any thoughts?

Re: Need help identifying cross sills

I believe the 49-1/2" cross sills are for the stepside's...As to what year you have you may be able to detail them off LMC or Classic Parts sites?

Those sills are for stepside beds. The boxes were the same for many years, 55-87 I think, mainly the fenders changed.
