Unless your car was originally equipped with 1LE fronts, the standard four-wheel disc set-up is Delco-Moraine, single-piston, iron calipers with 10.5" front rotors and PBR, single-piston, alum calipers with 11.7" rear rotors. And, yes, the auto parts fellow is wrong. BTW, all 82-92 four-wheel disc cars are RPO J65, regardless of caliper type or rotor size.
