Believe me when I say I haven't done it myself. I've had a couple friends help me along the way, but I would say 85% of the work or so I've done. That last 15% or so, it really helps to have friends involved *lol*. Plus, this forum has been an invaluable resource, as have the people who have done this type of work before me.
If I ever had to call a mechanic, to gauge his/her skills, I'd tell 'em I have a Trooper. If they can work on a Trooper, they can work on a VX. They share the exact same drive train, so any good Trooper mechanic will be a good VX mechanic.
