As for speedo correction, just get a scangageII. It has its own speedo adjusting software, just plug in the percentage and voila, accurate speedo on the scangage display. I synched mine with GPS so I know its pretty much dead on.
As for the gage faces, they are really nice! I got one, just need to add it to my list of things to do. They are really sharp and a great quality! The zombie hunting passes you made up are awesome as well!!!
I had some Jeeper/Zuks stop me on the way out and ask about our little VX convoy. They said they had never even seen one before, a lot less 3 in a row! I told them you guys did Dutch John bone stock, they didn't look they believed me. Oh well, we have pics and videos to prove it.
Back on topic...sorry.
