1949 Ford design or production issues

[40cpe]

I think I want a nice shoebox ford tudor. I know there were many improvements starting in '50. I'm thinking about a nice '49 that is too far away to go for a casual look. I would like from you that are knowledgeable of the '49 advice on things to look for that would be expensive or impossible to repair or modify. I tend to keep my cars for a long time and I don't want a car with issues that bug me, or worse, unsafe.

TIA for your thoughts.
