My 1967 Cuda Restoration

ive been reading your thread, and saw that youre using daytona hood springs for your AAR fiberglass hood.

couple of questions:
1. what year daytona, and any others that will interchange?
2. how much of a PITA were they to install?
3. any modification to the hinge itself required?
4. think i can put them on with the hinges and hood in the car?

thanks
Michael
