My New Toy 1968 Barracuda Fastback Formula S

Rolled my dash back today, my front speaker was damaged from trailering my car back and forth without the windshield in it when it got painted. Also a good time to pull the factory tach out since it did not work. I need to find a new speaker that I can install in there any suggestions would be appreciated and I am going to drive out to Hartland Michigan to Bob's Speedometer Service it's about an hour from me he said he will take care of the tach. Once those are taken care of then I can put the windshield back in.
