Thanks. Y'all gave me the idea to look at those years in the master parts catalog online. It just confused me after I finally found where they were. And if 1/16" (or 1/8") is the only difference in them on O.D. I'll need to measure again.
OCMP master parts list "cap" page.
It stinks to think that you have one item checked off your truck "need" list, then find out you have two of the wrong thing.
