All Junior Packards from 1935 on used standard 1/2" square head pipe plugs for fill and drain openings in the rear axle.

The 160's and 180's used an R-9A unit which has stronger internal parts then the R-9 used on the Junior cars. Bigger one-way clutch and 4 pinion planetary for example.
Look for the number cast on the side of the case.

Looks like Packard did cast the mounts "upside down" for 1935 and 1936.
The 1937 and newer cars that I am familiar with are the other way around and the pump that you have would work fine for those models.

I have an AC catalog from 1945 and was going to post some images from it but noticed that it was copyrighted by GM. I can send you copies of what I have if you PM me with your email address.

It looks like you have the correct type of pump for your car which is an AC Type X but the arm is upside down for the 1935 and 1936 cars.

Is this what you're looking for?

The left one should have an offset bend. I checked 2 of them and the parts book also shows the slight bend for the Monroe system.
The right one is straight

Looks like Phil has an oddball pump. Any that I have seen mount the other way, with the vacuum section on top.
You can easily check this by looking at the fuel pump mounting location on the engine block and comparing it to your pump. It can only mount one way.

Taxman,
The pump as pictured is upside down. The vacuum section is the one closest to the tape measure and the pump is installed with this section at the top. there should be 2 threaded openings in this section, an inlet and an outlet. The inlet or suction side should be connected to the wiper motor and the other side to the fitting on the intake manifold. You will need to bend up some new pieces of steel tubing to get this to work.

Sanford,
Your carburetor metering rod is assembled correctly. The WA-1 carburetors used by Packard had what Carter called a vacumeter setup to operate the metering rod. This used a vacuum piston to pull the rod down against a spring when power demand was low. The pin on the throttle linkage is designed to pull the metering rod up when the throttle is opened wide.
There is a very good description of the carburetor operation in the Serviceman's Training Booklet for Carburetors on this site.

I'm not sure about 23rd Series, but the 22nd Series originally used a hidden frame for the rear window which had the convertible top material wrapped around it, both inside and out. See Service counselor Vol. 22 No. 11 for pictures on page 44 under Water Leaks, Models 2259-79. This style rear window was installed in material that was a permanent part of the top assembly. I have only ever seen one car with this original type rear window still in place. Most cars were modified when the canvas tops were replaced by either a glass window in a zippered panel that could be folded in for better rear visibility or by a plastic window.
The parts book shows different numbers for the 23rd Series as well as a zipper assembly, so some changes were made. See parts Group numbers 31.0603, and 31.0625.

Kevin,

You might want to consider a cheap beater vehicle for the winter. The bodies and pot metal chrome trim on 1951 Packards don't take kindly to heavily salted roads.
That said, you will find that these cars are simple and reliable. I drove a 1951 Patrician as an everyday vehicle for several years in the early 60's with no problems in spite of not being gentle with it.
Engine, suspension, transmission and rear axle parts are still available from vendors that you will find on this site. Brake and electrical items can be found at your local parts store as long as you know what to ask for. The parts x-ref on this site is helpful for many of these things.
As others have said, it would be good to check the car out thouroughly wnen you get it and come back to this site for advice.
