Dear friends
Any one are able to tell me the correct length of the tube connecting and riveted to the two ends (each end have 2 rivets) of gear shift lever system ?
The best measure is taken 

, probably, from de center of the first rivet (the first from the front of UC) to the center of forth one (nearer to the back of UC).
I hope that you all understand what I am asking ! 

Our connection (tube) rotten away after more than 39 years on a military depot  

Thanking in advance
