I have a set of used cast iron Poston frame mounts to put a BBB engine in a "G" body car (Malibu, Regal, Cutlass, Grand Prix). They are in great shape and have grade 8 studs in them now but you can remove the studs and use bolts if you desire. The price is $60.00 shipped to the lower 48 or $50.00 if picked up. The parts are located in Bowling Green, Ky. I can take cash, paypal or a money order. Thanks.
