Hey All, I was wondering if anyone knows seat belts specs for a b310. I.E - bolt size, thread, etc. The guy who had the car before me took them out and put GM lap belts in. I've been looking on amazon for 3 point retractable seat belts and im not sure if a standard size will fit.

p.s. - i was working on my datto in an O'Reilly Auto Parts parking lot and a kid drove by in a minivan and said "nice car fag". Funny thing is he was the one driving a minivan.

Bolt size and thread are not part of the seat belt. You can simply thow out the GM bolt and use the Nissan bolt to bolt it to the car

well i dont have the bolt for the threaded hole at the top, the door pillar as I would call it. where would I get a bolt that would fit? Do I have to buy it from Nissan?

Easiest way is to go to a pick-n-pull or Ecology auto wrecking and get a bolt from a similar year Datsun, car or truck.

Or you could buy it from Nissan.
