The part number for the correct 28" radiator for my car is 3673053 per G.G. white book. My fender tag clearly shows 28. The 3673053 was used for the 400s and 440s auto or manual with heat only.

You definitely have an oddball with the 28" radiator. Not sure where you will find a replacement for that. Only 73-up had those, so very few used ones. You might have to fab up some brackets and go to an aftermarket 26" with more rows...

On the heater core, I'd look into getting yours repaired, the new ones (if you can find the application) are pretty bad, usually only lasting a season or 2.

On the heater core I had a hard time finding one, so I went to Rock Auto and purchased the one they offered. Hopefully it will last.
I still haven't found a original radiator that's useable. The one I have has to many stress cracks in the top tank. Looks like I'll be going with aftermarket one
