In addition, the 3 deg right and 3 deg left have opposite handed threads.
That means you can't fit 0 degree trunions to both sides without swapping out
vertical links. (I expect the 0 deg trunion will fit one or the other but I'm
not sure of that either) It is still a possibility, however. My TR6 had two 3
deg left trunions on it. A PO had fitted up a left hand vertical link and
trunion on the right side (probably after an accident) which made for some
really bizarre handling. Once I got that sorted out handling improved greatly.
It is possible that you have early trunions and later upper arms which
weren't meant to work together. Sometimes mix-n-match doesn't work so well.
