They appear to never have been used. There is a bunch of dust and dirt around the bezels, I did a quick wipe down. They look brand new. The chrome is very shiny.
The Fuel gauge comes with a sender, unk what the ohm range is.
The speedo is mechanical. I don’t have a cable for it but it has the standred sqaure drive, and my local speedo shop said it wound be very easy to make a custom cable for it.
The large gauges are 3 3/8 and small are 2 1/8.
Just updated with more photos. I gotta dig up the fuel sender, but you can see the oil pres, and oil temp senders, as well as the mounting brackets and hardware.
