I can take your helix spacer as partial trade towards a smooth 62mm spacer. If it's of any help.
If I were still in Miami, I would have done it; but now the Jeep is in Panama, so shipping would kill me. It's probably cheaper to have someone do it there; besides, I have a friend in Panama with a lathe (actually, a complete shop) who can probably do it for me for free... I just got to find the time during one of my monthly trips to panama to do this!
