Just thought Id pass along some info. I needed to install some spacers on my truck for some new wheels to fit correctly so I picked up a set of 4 from Sixityauto.com. They are 5x5.5 to 5x5.5 and are 1.5" thick. I'll post some pics in a few but they are a well built and fit perfectly. And I got all 4 for $99 instead of all of the other brands that were $80-100 for 2. I wouldnt hesitate to recommend their spacers or adapter.
