Part # 3884598 for the pressure plate and 3908960 for the disc. These are the 11" pieces for all 1965 - 1970 big block applications including special high performance. My parts book list the 70 454 (LS5 and LS6) with the same pressure plate but a different disc. There are some other GM applications for the Olds, Pontiac and Buick. $500 plus shipping.
