Pitman arm question

[JRN1967]

I'm building an AV8 with an F1 steering box. I want to use a drag link with tie rod ends.

Does anyone know what pitman arm will have the taper on the left or drivers side? What length arm should I buy? - John

If you don't have a clash situation due to split bones being where the pitman arm wants to be, a 32 arm will fit the F2 box.
I'm using a 32 arm on my 32 frame on my current build with a f1 box. It all works like stock as long as you have an original unsplit wishbone.
Without seeing your car it is hard to make a rock solid statement about what will work.
I show quite some detail in one of my videos.

Thanks Mart. I'm using an unsplit wishbone, with a 36 standard axle and 37 spindles.

Use the 35 36 pitman arm if you have it. Its the shortest and straight/ flat.

I think the change from inside to outside on the pitman arm was the 42 to 48 and also has a offset angle.

They all fit the F1 box, it uses the same sector as a 37 to 48 car box.

You will still need to split the index splines to get it were you want it on the sector

I'm using a 21A-3590 (or is it a 3550?) It's about 6" center to center of the holes. I had to put a slight twist in it so that the drag link would be aimed up at the steering arm without binding the tie rod end.

PS: I'm using a wishbone with a K member (home made) and an F! steering box that I cut the flange off and welded on a new flange made from 3/8" plate to Model A dimensions.

PPS: Keep the drag link to the inside. Otherwise, it will limit your steering when turning left.

Appreciate the responses and based on what Pete is saying its a good thing I asked. I wasn't aware there would be interference.

Thanks John
