Opinions on a restoration

I would go for the 74 ...it already has a title and frame rails are structural .....the roof could be considered structural too but a roof is so easy to change out, I did a roof replacement on a scamp which is the same body and its not hard just time consuming.

The 74 would be more unique at a car show because you rarely see them around......

The 72 would probably worth more but if your goal is to flip then I would say don't do either one and look for an easier way to make money.
