I have a spare set laying around and Im wanting to retrofit them to one of my thunderbirds. What model are these? I could measure all the specs but I can likely look them up.

Many Thanks

Hey Xx
I have need of these calipers - do you know they are functional and would you be willing to sell them, since they are extra for you?

I'm not sure about your retro fit question, so I cannot be of help that way.

Please let me know if you want to sell them and if they are working.

Best,
Mike D
