We designed this Hurst transmission crossmember to fit 1968-1972 GM A-bodies such as the Chevelle, Cutlass, 442, GTO, Tempest, LeMans, Skylark, and also the Grand Prix (G-Body) applications when installing a Tremec TKO 5-speed or Tremec Magnum 6-speed transmission. Much stronger than the stock unit, this crossmember helps maintain the correct transmission/driveshaft angle and is adjustable for both coupes and convertible chassis's. The crossmember has a a durable black powder coating and includes all necessary hardware for installation. Also fits El Camino, station wagons and other vehicles that are based off the A-body chassis. This crossmember is a great choice to replace your old beat up original crossmember and can be used with GM TH350, TH400, TH700R4 automatics along with many GM manual transmissions. Be sure to check out Hurst tunnel patch part #69510005 (available separately) designed specifically for transplanting a Tremec transmission in your A-body car.
