I'm trying to identify what this seat originally came in. Image searching on the internet has come up with some very similar looking results, but the side adjustment bracket is never the same?
Any ideas? As far as I know it is a Toyota seat, since it fits original mounting holes without modification.

 

Sorry I don't know, but maybe take that plastic cover off and look for any part #'s and google them, maybe find a year and model of fitment????

 

it's maybe a little bit modified

 

the key to this question is the seat rails; toyota moved to dual locking sliders in '86 or so, they use a cross-wire to unlock both at once.

it's difficult to see but the rails on that seat look like they are bolted on, including using wire wrap for upholstery(?) to secure at least that one rail?
