Mine arn't!
Thought the sierra was ready yesterday and even washed it! Then I found the nsf bottom suspension arm bent which was no doubt caused at croft last year by the hole in the ground at sunny out that I hit

so I removed the arm and then jacko off here who I share the unit with told me he had a cos 4x4 arb with new arms all poly bushed, so it would be rude not to fit them instead! just need 4 new arb mounting bolts then it should be done.
the 100E needs a new servo fitting and that hasn't arrived yet
