Ok guys been awhile since I been on here but getting geared up to get some things done. I have a 5 gauge cluster from a 66 mustang I want to put in my 65 that has the old cluster with the sweeping speedometer. I have an Autometer guage set under the dash with water, oil, and amp gauge. So I think all I need to work are fuel, speedometer, and background lighting on the new 66 gauges. I`m sure alot of you guys have done this upgrade to their cars, I`d love to hear some good ideas on how to do this, and of course I`d like to hear anything that gone wrong while doing this, as breaking things I`m working on seems to be the best talent I`ve shown thus far.
