Default Need some dimensions off of a 7hv, please help.

Compass owners,

I have a question about the pitch links. What is the difference between the 6hv and 7hv pitch links. Is the arm at the top ( the same for the 6hv and 7hv? I have a 6hv arm and it has a 3mm bolt, is the 7hv a larger bolt?

Also, I noticed that the delron rod is different between the 6hv and 7hv, is it the same diameter and just different lengths or is it a bigger rod?

Derlin tubes are the same diameter but on the 7HV they're quite a bit shorter. 7HV bolt that goes through the fork is also quite bigger. The fork itself is also different, its larger. So technically the 6HV derlin tube cut to size could fit the 7HV but not the other way around.
