You won't find a "new" casting, you're going to have to start contacting the Packard parts mongers to find a used pump or pump body. You might start by going thru the parts books and finding which years and models used the same pump and then contacting Kanters, Max Merritt, etc., but most if not all guys that would sell this pump as a rebuilt will require a rebuildable core which you don't have. If you don't have any luck there, then I'd suggest you go thru the PAC directory for members who have a car that uses the same pump, and just start calling them, hoping that one of them has a spare pump they're willing to sell.

It's a long, expensive process but cast iron can be repaired by welding. It requires the part to be heated first, then welded, and then cooled at a very gradual rate over a period of days or weeks. One place I know that does such repairs is Automotive Restorations on Rte 22 East in Lebanon, New Jersey. Ask for Steve. But it's not going to be inexpensive.

The crack in your casting was probably caused by some jackass tightening the packing nut when there was no packing present.

Still need to know exactly which model you are working on. First 3 digits of the serial number would be a good start. Then maybe someone here can fix you up with a pump, or a pump casting.

I have a model 803
After that is a dash 1266, I know the 12 is for 12th series but what is the 66 for?
The crack around the bushing has been there for quite some time, its really rusted.

No, the 12 in 1266 doesn't denote 12th series. The 803 decodes into the Eight chassis (320 ci engine) on the 127 inch wheelbase of the 12th series with the 5 passenger 4-door sedan body. The 1266 is simply the sequential production number of that body type. I don't recall the base number for the sequence for 1935, it was probably 10, meaning that your particular car is the 1266 - 10 or 1256th car with that chassis and body constructed to date.

Best of luck in finding another pump.

Per the parts book pg. 128, the waterpump fits 33-36 Super 8, and 35-36 Standard 8. My guess is there is one out there.

Could the crack be epoxed or JB-welded?

Not reliably. There's too much pressure exerted from the packing and packing nut.
