Hey im mike and i recently picked up an 83 rx7. Im not sure which model it is because all the badges were missing when i got it. Its a 12a with a 5 speed and posi rear, but im planning a 13b swap on it and ive been told this is the best place to find info on them.

as soon as i get some pics ill put them up

 

welcome mike. rear disk brakes and lsd makes it a gsl.

 

it has rear drum not disk
