My truck is a 65 Step Side the bumper I bought is 60-66.
The Classic Industries Catalog shows the same bumper was used on step sides 60-66.

the bumpers change from 62-63 due to different frame width
the bolt centres on the inner bolts on a 62 rear bumper are 40". the bolt centres on a 63- should be about 32-34"
