My cousin from abroad has a full metal head and I was thinking about putting it on my T-rex 500. Can someone with a micrometer or vernier give me the diameter of the 550 mainshaft please? Thanks

I measured it today and that's what I got. 8mm's.
Helimax Axe CP, T-Rex SA & 550EP Hurricane The only thing that's constant is change!
