1969 H/O back drive rod

I'm pretty certain that '68 didn't have one (key in the dash); however, I have a few '69-'72. Email me direct: drolds1@bellsouth.net. Thanks, Bob.

Correct. 1969 was the first year that the Feds mandated the locking steering column and shifter.

As for the correct parts for a 1969 (as opposed to parts that will work), the story is complex. There were two designs for the backdrive linkage, a first design and a second design. The first type uses a rod that runs directly from the steering column lever to the trans lever, and the trans lever is triangular. The second design looks like the 1970-up cars (and the column-shifted linkage) where there's an equalizer that runs from the frame to the trans. I'm not sure when the switch was made, but the drawing in the PIM that shows both designs is dated Oct 31, 1968, so presumably all 69 H/Os came with the second design.

Some of these parts are common with the ones for a column shift linkage. The second design equalizer is shown as P/N 402988 in the Oct 1968 PIM drawing. My Sept 1968 Parts book shows this as also being common with the 1969 column shift AT cars. The Jan 1972 parts book only shows this for 1969 L6 cars with console (go figure) and shows a different P/N for the 1970-72 cars. That newer parts book also shows a different P/N for the 1968-69 column shift cars.

The rod that runs from the steering column to the equalizer is P/N 404126 according to that Oct 1968 PIM drawing. The Parts Book shows this as used on all second design 1969 floor shift AT cars and also on 1969-70 floor shift MT cars. All the other small parts (equalizer bracket on the frame, bushings, trunnions, springs) are common with the column shift cars.

Now, I suspect that the later year parts will work just fine, and frankly no one will ever know if they are not the correct P/N.

Joe,
Your vast knowledge is always appreciated and imo second to none. However in this case my homework says I need the first design as my car has the triangular lever and the holes in the frame where the other type bracket was used (most common on a bodies) were never used or had bolts run through them. I think this rod also bends in the opposite direction then the others going towards the trans.

Yup, I just saw your FB post. That first-design rod is P/N 404139, and it's unique to early 1969 floor shift AT cars.
