I am also looking for a 12 or 13 lb pressure cap. My 1953 has a 1" deep filler neck, not the standard 3/4" that most other vehicle brands seem to have used.

Does anyone have a 13 lb. cap cross-reference number that will work for this 1" depth? (Or a good used cap to sell?)

I can find 13 lb/3/4" depth caps, and 7 lb/1" depth caps, but not the 13 lb/1" variety.

I believe the numbers listed in the Packard cross-reference list are for 3/4" depth. (Did Packard use both 3/4" and 1" deep radiator necks from 51-54? Both radiators I have are 1" deep).

Many thanks for the assistance, as always.
