I would like some help with correct spark plug, condenser, distributor, and rotor parts for this motor AND recommendations on where to buy them. Sources are slim here in New Mexico.

Important to know if you engine has 10mm spark plugs as it did originally, or if it has been converted to 14mm either by having been drilled and rethreaded, or by a replacement cylinder head. Good plugs readily available at any good parts store in either case.

Kanter sells complete tune-up kits, I'm sure Max Merrit does as well. But all of the components are available individually from better local auto parts stores but you may have to help a bit with part numbers. The part numbers for points, condensor, cap & rotor have been posted here many times. If you browse a bit you'll find it or perhaps someone with a bit more time will repeat it for you. The current points will differ slightly in the mounting from the OEM points but will work just fine.

Lovely cars, those 48 Custom 8s, had one for many years (pix below).

Hey 48Packard, Beautiful 2252 you have there. Santa Fe is my old stomping grounds. I know some Packard owners there who can help you. PM me and we can discuss off line.

Edit: O_D made a mistake, thought it was 48Packard's.

Here's the most recent numbers I have for an AutoLite IGT:

NAPA/Echlin
Points CS721A
Condensor AL 869
Rotor AL 63
Cap AL 66
Coil IC-7

Standard Ignition
Points AL5255XP
Condensor AL 118X
Rotor AL 99
Cap AL 97
Coil UC 14X

I can't guarantee all these numbers are active, some could have been superceeded or even discontinued though I think all the Echlin #s are still active. Others will know.

Current spark plug recommendations from AutoLite:

if 10mm, #3136
if 14 mm, #308
