is my car in any way special/rare or more valuable than any other? 70 340.

Any recommendations on a set? The only ones that I saw wanted me cut holes in the floor pan. Not really into that.

They have a set that contour to the floor pan. Some minor trimming is required, you weld the entire length to the under side of the pan. Nice strong piece when done and no cutting of the floor pan.
