The Ford Barn

I am wanting to use a later pitman arm that has a tapered hole at the bottom on my 34, not a made on ball. The pitman arms I have have the 4 wider grooves clocked in a different position. Did Ford make a pitman arm with the grooves the same as 32-34 but will have a tapered hole?

Heres what I have:

1932-1934

The later one I have:

I know I can simply cut the arm off the later one and tig it in a different position...but before I get too carried away I am just weighing my options.

file the 4 flats into another spline and you can clock it anywhere you want---barry

Chris,
Barry is right... just use a triangle file and make them into teeth.... doesn't take that long

Ditto Barry and Zach! A small triangular file will cut the grooves nicely. It doesn't matter if those 4 grooves are a bit sloppy- the other grooves will fit very well and all will be well.

Ditto above, don't try to make them the right size, purposely make them deeper than the others, then it will seat on the precision cut proper splines.

Thanks guys, makes perfect sense...I had one of those "why didn't I think of that" moments

Chris,

It is only the '33-'34 pitman arm that has a built-in ball on the end (like a Model A arm). The '32 pitman arm has a tapered hole on the small end for the tapered drag link ball stud which is attached to the arm with a low-crown slotted hex nut and cotter pin. The "clocking" is similar, but not the same as '33-'34.

Very early '33s also had a pitman arm with a replaceable ball stud.
