rear caliper labelled R?

im looking to buy a rear caliper for my 92 s13 and the person im buying the caliper off ofsays its labelled “R” does that mean its the right rear caliper? He doesn’t know either.

i’d like to know so i dont end up buying the rear passenger side caliper since i need the drivers rear only.

let me know,

DK

Yes, “R” means right. so its the passenger side

look at it, the bleeder screw goes on top when its attached to the car, most stampings are correded over and illegible

thanks boys.
