Ed, the OP sent me a Visitors Message. Didn't say what year or series his truck is...so I read thru his posts and found this one.

I doubt anyone would have reproduced a 534 air cleaner decal, as the demand is slim and none.

If the other engine and air cleaner decals are the same as passenger cars used, dearbornclassics.com has repopped them, has pics of them all, and pages of them listed.

Dearborn Classics is located in Bend, Oregon. Call 800-252-7427, and request a free catalog by snail mail.

None of these car/truck decals were available from Ford AFAIK, as there are no part numbers for any of them.
