I tangled the terms on the 4 speed terms I used.
We know the Code 77W was the standard M20 up to 3.55 gears
According to John V. - the Code 779 M20 with special speedo gear was the default with 3.90
And Code 778 was the Spec Eqpt M21 Close Ratio with 3.90
Majority of 65 3.90 cars were ordered with the M21
Seymore's car is #778 with M21
Mine is #779 with M20
Tarheels is #779 with M20
The powetrain charts that PHS sends out were done themselves
Some errors on the 65 chart they made.
None of the 3 cars listed above have the #591 Speedo Adapter.
All 3 have Code #534 HD Fan = $3.12 option
Actually they all 3 show #535 because all 3 also had Option 531 SoftRay ALL as well
The 4th car is a WS M20 3.55 for cross reference
All 4 are Black.
Seymore's 65 M21 3.90
Tarheel's 65 M20 3.90
My 65 M20 3.90
Random 65 M20
3.55
