 Hi;

In Roger Williams book "How to Restore Triumph TR5/250 & TR6", he discusses
the trailing arm brackets.
He says that "At commission numbers CP52867/CC61570 bracket 1555502 (3
notches) was fitted to the inside mounting and 141398 (1 notch bracket) on
the outside...."
"Furthermore, it is not generally appreciated that at the same time as the
mounting bracket 'notches' were changed, a change occurred to the trailing
arm castings, and the angles varied from the earlier castings. ..
Fortunately, Triumph's casting sub-contractor was meticulous in
incorporating the date of the casting on the outside of each trailing arm."

    Would someone tell me, please,  if a trailing arm with a date of 14/5/71
would be before or after CC61570?  Is the change in the trailing arm obvious
enough that I should be able to see it?

        Thank you
