Projects Parts Question

Hi,
I am looking for a project car I was originally going to get a 1964 Rambler but the frame turned out to be rusted out. I stumbled upon a 1964 Buick wildcat 2 door and a 1950 Chrysler Royal. My question is, is it hard to find parts for these cars or does anyone know where I could find any.

Thanks

 

buy the buick, parts are easy to find and it is a much faster car

 

... faster as-is and probably easier to get parts for, and maybe the Chrysler needs the 440 the OP
was thinking of using in the Rambler.
What does the OP intend to do with either is the base question.

I plan to restore either of the vi
