My 71 442 is missing the front center seat belts for the bench seat. I am trying to find the correct belts, but need to determine the correct length for both the male and female sections. I know it's difficult to measure as they go through the seat. If anyone has loose ones or will go through the effort of measuring as best they can I would really appreciate it. 71 may be the last year for the adjustable female belt. As I research this, 72 may be the start of the male adjustable belts. Thanks.
