The Hurst engineers designed this transmission crossmember specifically for 1964-1967 Pontiac GTO, Tempest and Le Mans convertibles when either replacing the old stock crossmember, or installing a Tremec TKO 5-speed transmission conversion. Much stronger than the stock unit, this crossmember helps maintain the correct transmission/driveshaft angle and includes all necessary hardware for installation. Fabricated from 3/16-inch thick cold rolled steel, mig welded for strength and features a durable black powdercoating. Also fits GM TH350, TH400, TH700R4 transmissions along with many GM manual transmissions. Note: Does Not fit Hardtop or Sedan models.
