TR6 TR-6 Rear Trailing Arms

[JC1]

Hello.. My understanding is that all TR-6 trailing arms (either right or left) were identical throughout all years. The only thing that changed, during 1971 production, were the brackets
(1 and 2 notches) to )(1 and 3 notches) and the springs.
Is this correct ?

Thanks

Looks right to me JC

I have two slightly different 4A arms, small differences in the casting. Know that 4A arms do not have the post for the rebound stop as does the 6.
