I'm trying to figure our what the stated dimension from JM represents. I want to upgrade the arms on both my Stella 10 & 20k.
The standard 20k arm will fit on the 10k, so where I'm really going is if the JM 10k arm is close enough to the stock 20k then I'll just swap them over and buy one for the 20k instead of having to buy both.
I'm also interested in just how much longer each of the upgrades is in comparison to stock so I can gauge the actual benefit.
