Been there, done that. And those seatbelts ARE warranted for life. That thread has a direct quotation from the warranty manual. Call 1-800-NISSAN-1 if the dealer refuses to cooperate. The dealer gets paid by Nissan to do the work...they have no incentive to refuse to honor the warranty.
There is no recall to replace the auto belts with manual belts. When these cars were made, passive restraint was required. Carmakers could choose between airbags, door mounted belts, or motorized belts. Nissan achieved that by putting motorized belts in the coupe/hatchback and door-mounted belts in the convertible. There will be no recall removing what, at the time, was a federally mandated safety item.
And the S14 seatbelt mods should be safe as long as you aren't using spacers. With OEM S13 manual belts, the upper belt-loop is BEHIND the side panel and uses the same length of bolt as the S14...
There's a "how-to" on here telling people to use a longer bolt and spacers to bring the belt loop outside the panel...this is NOT safe as it creates leverage with the longer bolt that increases the likelihood of failure of the bolts. Use the shorter bolt with no spacers and keep that loop tight against the car frame and it will be fine.
Personally, I wouldn't touch anything pertaining to seat belts...if I get killed, I want someone to be accountable other than myself.
