TR4/4A tr4 tie rod end/ball joint - technical question

I have a '62 tr4 with ball-joints for the steering control arms.

Because I am lowering the car and want to eliminate bump steer characteristics, I am considering a "pin type" kit available from many racing supply shops that allow you to lower the the mounting of the ball joint (actually you use a heim joint instead of a ball joint). please reserve judgement on my choice of heim joints for now. I do know the pros/cons of using heim joints.

anyways, the common tapers available in these "pins" are 7 degree (pinto/mustang II) or 10 degree (GM). does anyone know the taper/degrees on a TR4 control arm (or corresponding ball joint stud)?

if someone could at least provide me with the taper (in degrees), I could either buy something off the rack or you can also get a reamer and do your own taper (less desirable).

if the taper is not widely known, maybe someone could correct me here; you could also measure on your own right?

measure the upper diameter of the hole on the top side of the steering arm, the lower diameter of the hole on the steering arm and then the "thickness" of the arm at the vertical centerline of the hole where the ball joint stud inserts. ...correct? if you took the measurements and drew it up on paper using a straightedge and protractor you'd be able to determine the correct angle of the taper from the upper hole to the lower hole....correct?

thanks. wes
 
Easier and more accurate, IMO, to measure an old pin. But what you describe should work, if the hole in the vertical link hasn't been damaged or distorted at the ends.
