70 duster 3 speed on floor

I can clear some of this up...... First there is no such thing as a 'four speed hump' since the A-230 3-speed with floor shift used the same hump.

The A-903 has no mounting bosses for a floor shifter, these were column shift only.

The A-230 was also available with 383 4-bbl engines in B and E bodies and in trucks too, but the truck version was column shift only.

1970 & newer /6 floor shift 3-speed cars were made, some are also 4-doors, but they seem to be fairly scarce. Even scarcer with a V-8.

For anyone wondering what their 1970 up 3-speed car came with for a transmission, what is the transmission code on your fender tag, broadcast sheet or other original document?
