My 1956 Clipper Custom has the Carter fuel system including the filter and I recently got an NOS ceramic insert for it. Fortunately the glass is still intact so no need to replace the whole thing. The NORS filters I have were used on earlier models and are identical to those on my 1951-1954 Packards other than having a paper filter. Somewhere I have a filter assembly that is much taller which may have been in one of my prewar Packards but I’m not sure.

If you can't find one sooner, I have NORS AC filter assemblies at my Oregon shop and can check if any are actually spares. They are identical to the originals but have a more easily replaceable filter element.

The engine number would tell if it is correct or not as they are coded to the year and model. It is located on the driver side of the block and is stamped on a flat boss, probably year the upper edge below the head. Different years and models had it anywhere from above the starter to farther forward but it was always on that side.

Yes, I believe that the upper side trim is from a later model (maybe 1951-1952) but the hood ornament looks correct. There were several different ornaments and I believe that the cormorant was optional on any that did not have it as standard equipment.

The ornament is actually a pelican from the Packard heraldry but more often referred to as another seabird, the cormorant. As I only ever owned one Packard in this era and it was a hearse so I cannot advise on the model of this one without knowing the vehicle number.

This page explains spark plugs and coil polarity far better than I could. There are many others here on this site and elsewhere that talk about spark plugs and the importance of setting them correctly with the proper gap.

Posting the question once is sufficient so how about deleting the other four?

The wheel covers on my Henney-Packards are roughly 12.75” dia according to my notes and had 16” wheels but I’m not there to double check. However, I have several others from both 15” and 16” wheels and I don’t recall noticing any difference in diameter but if you want I can check in a few weeks when I’m back at my shop.

I noticed that too. This car has been severely butchered (in my opinion) and would take much to make it stock again.

Yes, indeed it would! That would be a great setting for it with my chauffeur waiting while we have lunch.

I never saw a 1954 long wheelbase car with Cavalier trim and the odd 1953 rear fender script on the trunk. Very interesting!

It also has factory A/C rear fender scoops but no dash controls. Where the controls should be on top of the steering column is what appears to be a shift lever sticking straight up. Over all a very odd and mixed up car.
