Tie rod taper

Absolutely totally from memory..... the only outer tie rod tapers
that are even close to being the same are 1971/73 Mustang
and the Granada/Monarch, and even those aren't exactly the
same.
I never looked closely at Pinto stuff though- those pins are
pretty small.
There was a Moog publication that listed most of the critical
dimensions, including thread dia, pitch and taper. (Taper was
not listed in degrees, it gave minimum and maximum dia and
the distance between those two specs. It was called a Moog
addendum or supplement or some such thing. I have not
seen one in years though. It may have been a one-time thing
because it makes the lives of your competitors in the suspension
business very easy. There also were a very small sample of those
same specs in some Moog catalogs, but only Pop A stuff (very
fast moving parts). I seriously doubt you'll find any such info
officially from Moog now, particularly since Federal-Mogul is their
parent organization these days.
I still work in the suspension business for a manufacturer- Moog
and their corporate decision-making is a daily source of amusement
for us.

I always bought new ones. I'm thinking the angles are like 7* and 10* degrees. Most time they are measured in inch taper per foot (or other). Again I suggest to buy new ones for the application. BTW, it's very hard to tell the two apart and when test fitting you may think it's right when in fact it's the wrong one. This is often a mistake made when upgrading to disc brakes using Granada spindles.

Although, without knowing the distance between the diameters you can't really calculate the taper angle.

Yeah, that's pretty much the listing. Amazing..... hadn't seen one
of those in a long time.
Ours were custom made but Speedway Motors has a few
of the more common taper drills. We'd just weld up the holes
and taper drill to match the specs of whatever we were dealing with.....

I had to get one of those tapered reamers to fix a spindle to A-Arm adapter... I could have sworn there was a reference on Speedway (or perhaps another dealer) that referenced them as Ford versus GM taper. Do you know if Ford used different tapers during the 60s-70s? Just curious.

That I do not know for sure. During that time, they seemed to be
fond of increasing stud diameters on tie rods but they seemed to
leave the ball joint pins alone......at least on the Mustang line.
I've only got that generalization to share.
To get bigger brakes, some folks were swapping entire T-bird
spindles onto the Mustangs back in the dark ages and they
needed tapered adapters to do it. I seem to recall the BJ tapers
were similar but the stud diameter increase was huge.
Sorry, not a lot of help.....
