There were two different flexplates (and harmonic balancers) used in 1979, because there were two different 460 engines.

There is no serial number or production date break, because this was a running change.

D1SZ6375A .. Flexplate - Use without weighted spacer.

Fits 1971/73 429 / 1971/78 460, and 1979 460, ALL with a block casting number of: D1VE-AB.

D9TZ6375A .. Flexplate -Use with weighted spacer

Fits: 1979 460 ALL w/a block casting number of D9TE-AB.

The car & truck parts catalog do not list a tooth count for either flexplate.
