Bandit400, I paid around $900 for the kit. I am OK with you guys using the design. When you place the order, just put in the comments that you want to use the graphics that were used on order 115641. The graphics department contact is Alaina Westberg and she can assist you with any changes. She was awesome to work with.
As far as the 4” gauges, they should fit fine, just a little slop in the hole. You will probably have yours installed before mine is on the road.
