Does anyone know what size and what direction thread i need for the rose joint at the rearset end of the gear change rod?

Ive got a new rod coming but the rose joints have been welded to the rod at some point so cant tell what thread etc they are.

i would imagin an M6 right hand thread, a m6 A2 coupler, and 2 x A2 M6 nuts to lock the coupler, rod and rose joint?
