If I wasn't planning on doing any work to the suspension, then I often placed jackstands on my '56 under the suspension components, the axle shaft tube in the rear and the lower control arm in front. Where the stands were place depended on what service was planned.

I don't know the correct answer to the original question, but in looking at the lovely piece of Packard advertising artwork that Richard Lambert has provided, we need to remember that display chassis prepared for showrooms were generally "dressed up" for eye appeal and could contain features not available on regular production.

You asking about the wood-spoke senior artillery wheels offered 1936 and earlier (17 inch and larger) or the later smaller diameter stamped steel artillery wheels?

No one making repros of either artillery wheel type that I'm aware of.

Many good carburetor rebuilders around, Daytona Parts in New Smyrna Beach, Florida among the very best.

Mechanical type pressure gauges are generally based on the "bourdon tube" mechanism, not "Bordon". Google "bourdon tube" for more info, very elegant yet simple.

The Utica plant engine number prefix will tell you if a particular V8 engine was built with a flywheel or a flex-plate. There was no available Utica code for a 5688 (Caribbean) motor with a flywheel and I believe the same was true for 1955.

Some years ago I purchased a very nice quality 2_ply indoor cover from Auto-Chic in Dover, NJ and I highly recommend them, the fit was perfect. You'd have to check with them to see if they have the patterns for a 1953 Caribbean.

I don't know about that era but prewar, around 1935 and prior, factory rebuilt short blocks were painted Crane Gray.

I would hope they are still available, the Steele part number for a pair of the rubber cups is 30-0292-11. They were used 1933 thru 1939 on the Senior 8 cylinder cars.

That driver's side snubber appears to be the same one they used for many years. I'd consider disassembling it and replacing the rubber cushions.
