Steering boxes

[340 Dart]

I have a 74 Duster I want to put a manual steering box in.
I have found a couple of B and E body boxes close to me and I think they will bolt up but are the splines the same?

I assume you are converting from power steering to manual. Starting in 1973 A body cars used a large sector power steering box. A B and E manual boxes all have the small sector. You need a manual box out of a C body or possibly a B Van up thru 88. I know that a manual out of a C body will work in an A body but I'm guessing about the van box, never having actually done that. You will also need a power to manual adapter as the power and manual steering columns are different lengths. Firm Feel, Steer and Gear, Mancini racing (I think) have the adapter. I think some Chrysler dealers may also have them but I don't have a part number.

Thanks Pyp. Yes I want to convert from power to manual.

The last time I did it I used the adaptor from Mancini, but I got the box from another "A" body.

This time though I can't find a "A" manual box.

Thanks for the info.

You can still get a pitman arm for a 74 A-body for either sector size.

If you get a manual box with a small sector, get Moog K7075. It is listed for 74 Duster with M/S.

Moog K7076 is large sector and is listed for 74 Duster with P/S.

I believe the manual boxes are the same except for ratio. Many years ago I had a box in one of my 69 runners go bad, and I got a box from (I believe it was) a64 A body and installed it without issue. That box is still in that car (which is on the far side of my shop)
