I'm looking to nail down the different lengths of the steering column couplers. (I cant wait for Carlisle this year. I have so much research I want to do.)

This is what I think I know so far....


3" couplers used on;
All 66-73 models except 73-74 B bodies. They used a big rubber knuckle type coupler.

3-1/2" couplers used on;
74-76 A Bodies - Dart, Dart Sport, Duster, Swinger, Valiant
75-79 B Bodies - Roadrunner, Fury, Monaco, Magnum
74 E Bodies - Barracuda, Challenger
76-80 F Bodies - Aspen, Volare
77-89 M Bodies - Diplomat, Lebaron, Fifth Ave, New Yorker
74-93 Dodge D & W Series Trucks
74-93 Dodge B Series Vans


Can I get a confirmation on the length used on unmolested 73 and 74 cars because it looks like the length change to the 3-1/2" coupler happened in 1974.

I'm pretty sure manual or power has nothing to do with the length of the couple just the spline size. The manual steering spline is about an 1/8" bigger.

I'd also be interested in confirmation of coupler lengths on F bodies, M bodies and all years of Dodge trucks.
