On post CT20,XXX TR4 trunnions, the vertical link threads cut the same 
direction for both sides (clockwise to screw trunnions on) but, they are 
'sided' due 
to the 3 degree castor.
Side note: pre-TR4A trunnions have threaded link sections 2-3 times longer 
than TR4As, 5s, and 6s and seem to last a lot longer there. My trunnions were 
perfect in threaded part even though the steel cross shafts had eaten through 
the brass A-arm bushes and into the cast iron a-arms! (I had to toss the four 
lower a-arms) But I was able to buy replacement trunnion cross shafts from 
RevingtonTR to press into my old trunnions saving me from buying new trunnion$.
TR4As and newer TRs have a different trunnion scheme - easier for DYI 
rebuilds - but the threaded link portion that seems to last forever on the 
earlier 
cars gets trashed fairly early on later cars..

the second 20,000 TR4s have the 3 degree slanted trunnions.

Which means there is a right and a left, right?  Do they have right and left 
hand threads (like the TR6)?
