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 anyone verify the length coupler on their year/model truck from say 61-93.

I'd be willing to trade a coupler seal clamp/retainer for a picture and length.

These are the couplers;

My 79 D100 only has the rag joint at the steering box. No coupler. I will get pics of the coupler on my 84 after I get off work. It uses the type in your pic.

Thanks!

Don't forget spline diameter, trucks were typically larger since most used Saginaw boxes.

Also, trucks pre 80 or so tended to use Saginaw couplers vs the Mopar style.

not truck related, but my 74 'runner has the 3 1/2" coupler. The ex's 73 had the big rubber one..
