1972 Duster 340 3speed

I crawled under there, damn near snapped my neck, matched the numbers of the VIN to the motor, trans, rad support door, dash, and package tray. In NC the DMV inspector did the same to produce a title.

VS29H in VIN. Numbers on block on passenger side match body number, match trans case, match rad support, match package tray. What I need to go and check is the trans code on the fender tag. Car is a special order 3 speed, no rally dash, sharktooth grill.
