1964 Instrument Cluster

[1964SS]

Can someone please recommend a place or individual that restores/updates instrument clusters for our trucks. I want to replace my ammeter with a voltmeter & add a clock along with a tachometer. I combed through some threads and ran across a member (TBone). However, he quoted me a price for the Voltmeter but for some reason has not replied back to multiple emails since the initial contact. I'm ready to complete this process and get the cluster installed. Any information will be greatly appreciated! Thank you all for such a great site to keep these precious gem's on the road!
