Track Rod End Screw Thread - Chris KC - 06-10-2022

I believe the track rod end adjustment thread is 3/4" x 20 tpi - would I be correct in guessing it's Whitworth thread form rather than BSC? Anyone know please?

Tracy Tools' website offers 3/4" x 20 in both BSC and Whitworth thread forms. 
The two are different though (BSC is a 60 degree tooth angle vs 55 for Whitworth).

Thanks Charles - I've sent you a p.m.

Just for closure, Charles very kindly lent me his whitform thread die and the new thread is indistinguishable from old by eye.
The job is now done, back on the car and functioning.

Charles, I have p.m.'d you - don't forget to send me your return address!!
