Pitman arm question

[dICKj]

Can l use my 1974 Duster power steering pitman arm on my swapped-in 1970 manual steering box?

The sector shaft sizes are different, and if you look, they are probably different in the way the attach to the center link. '70 from the bottom up, and '74 from the top down. Pittman, idler, and center link changed to the later style in 1973. Moog K7075 should be the one you need.

From your comment I gather that I will have to change to idler and center link too?

Sector size is the same. The 72 back used a smaller sector shaft on PS only.

Right, but the large PS arm from his '74 won't work with his manual gear, will it?

No, with the right Pittman arm you'll be good to go.

It does call for two different Pittman arms. Moog K-7075 for manual and K-7076 for PS.

Here's a page that has a lot of crossover numbers for Moog K7075 at the bottom. It can help you to find what you need.

If you have:

• a 73-76 center link and idler arm

You want to run:

• a small sector 72-down P/S or A/B/E body manual steering gear

You need:

• 73-76 A-body manual pitman arm. Because the manual steering gears did not change their sector size in A/B/E models. AND those pitman to centerlink studs point downward.
