I have two questions concerning seat belts for a SanJose-built 67 fastback
(1) In a recent post Jeff warned to make sure the rear seat belts were bolted in BEFORE the rear quarter trim panels (large pieces, one on each side of the rear seat) were installed. I can see how it would be much easier to install the seat belt bolts without those panels in place, but my question is whether or not it is possible to install the seat belts AFTER the panels, even though doing appears to me to be more difficult. I just realized my rear belts are torn thus I'll have to find others, but the trim panels are ready to go, hence my question.
(2) Is it common to find the front seat belt retractors in different extended lengths? See attached picture. I have several sets and I find that retractors with date stamps in 1966 extend further than those with 67 dates. I find this odd. Perhaps it's common?
