lots of good bed info on the
mar-k.com site
like the bed sides are the same from 54 thru 87 except for the fender bolt holes
also i didn't use bed angle strips, just 1.25x1.25x1/8 angle iron.
it was a cost effective method to re-new the bed angles.
for my mini-tubs: i cut the metal out of the bed side with a jigsaw
cut 3'' wide 10ga steel to fit the arc and just re-used the cutout from the bed side.
it makes the grooves in the bed side match the mini-tubs
