Having Flywheel and Harmonic Balancer issues:Please Help. Thanks

[Ben84gt]

1971 302 in an 84 Gt. The Ati Balancer reads A370820 but i cant find that number on summit or a cross reference anywhere. Anybody know if maybe they just dont make this older one anymore? Thanks in advance

If it s a 71 302 it wpll use a 28 oz flywheel and balancer. Does the balancer have a large or small counter weight?
