the USDM s13 is the only s13 on earth that has auto belts...
all canadian cars have manual ones.
i do have a full coupe interior with belts but it is spoken for, i will have a tan coupe conversion soon.
i have had a set of manual belts sitting around for a while. i used to sell a ton of them on here last year.
