5.9 Magnum flex plate too small??!?!?!?!?

Check with ur friendly neibourhood tranny shop. What year is the tranny? If ur tranny is 1967 and newer u can find a converter easy, if 1966 and older u will likely have to get one made. PTC, Ultimate, dynamic can build u one. Ur converter is called the 091 which was found behind all low performance cars. The 764 is which u need. It has the higher stall speed. The 764 was put behind most hi performance engines from 1968 to 1975 or so. Kim
