Opinions on a restoration

DartNut & KrazyKuda - Thanks for your votes.

KrazyKuda - Honestly I am not sure which will be the easier fix roof vs frame rails

VitaminDemon - thanks for your vote. Have you actually done both a roof swap and replaced frame rails?

Rocky_Js - Re-sale prices are a guess at best. They are all over the place. Haggerty gives the edge to the 72 but that is a factory v8 car, they don't list a price for a 6 cylinder car.

If we sale this car I don't expect to make money, but if I am going to do it I would just as soon build the more valuable car unless it is going to be far more costly or difficult. I am actually building it for my son.

Thanks for everyone's opinion so far.
Currently it is 3 in favor of the 72 and only one for the poor unloved 74.

Thanks All
