Install a clock in a 77 Cordoba

[41indian]

Hi, I want to put a clock in my non clock 77 Cordoba.
I have the clock and face plate, what else do I need

This the one mounted in the pass side dash like later ones

If so , I think all you need is the clock, and said dash pad

I added one to the 78 Magnum I used to own that way
