I was cleaning out my junk and found my old Autometer 5" Sport-Comp 10,000 RPM that I was using before I got my shift light tach. Right after I got it the light blew in it and I sent it back to get the light repaired. Instead of fixing it they sent me a new one. It does not have a lot of use. Brand new it sells for $130.00. I will sell it for $75.00 plus the ride/Paypal. It has the brown wire cut in the back for a 6 cylinder. You will have to solder it back together for a V8.
