Call ARB in Renton (425-264-1391) and ask who they recommend since they know the shops in your area personally. This way you can get an actual ARB dealer and not just some shop that buys the parts from random wholesalers and resells them.
We are about 4hrs south so a bit out of the way but if you wanted to make a trip to Portland OR, let us know. We stock all the parts.
