Yeah, that cluster looks really good. I'm still thinking about it. I pieced together a nice factory cluster with the trip speedo, a clock, and the tach. I have the original wiring harness for a tach car, and a modified one made from a non-tach car (the tach one requires different underdash and engine wiring -- $$$). I could probably get close to the cost of that JME cluster by selling my Frankenstein on ebay.
I really want a tach, but I also really want an oil pressure guage and an ammeter. Don't want to hack the console or anywhere else, so I'm still looking for options that aren't tacky.
I'm playing with the idea of putting a '68 oil pressure guage in the clock hole, it's the same size and such and would look oem unless someone knew better.
