[Fot] TR4-6 front end technical queries

[Terry and Cindy]

I have bought what was supposedly a new TR6 trunnion only to find it had
zero caster and so the top ball joint does not align with the arms. Also,
its sloppier than my 30 year old STANPART one on a band new vertical link.
Who makes a good quality 3 degree TR6 type trunnion??

Can anyone explain the differences in the steering arms that bolt to the
vertical link???? My issue is the steering rack appears to long as the tie
rod ends sit out too far even when screwed fully in. I suspect a mis-match
with rack and arms.   TR4 early (127830/127831), TR4 mid (129386/129387)
TR4 late(134541/134542) , TR250, TR6 (307211/307212). 

Finally, what is the current thinking on caster angle. I have tried some jag
top ball joints which will give about an extra 1.5 degrees caster.
