I just put the seats in my 74. Because I want to remove them from time to
time , I drilled out all the nuts and welded bolts to my seat frames. Then I
dropped the seats in and from the bottom of the car I used a thick fender washer
and Nylon locking nut. Now I can remove and install with ease.
THnx
Pat
PS Gonna get her inspected today !
