Original gauges vs replacement question/ help needed

[Heinz55]

I have a 55 TF Chevy. Almost done installing the new wiring harness (Painless product), just have the dash left to do. I have the original gauge cluster, but I have no idea if they work. I will be replacing gas tank with a s-10 gas tank soon, which means I need a new fuel sender and gauge? My wife likes the look of the old gauges, but I don't know where to start making them work with the new drive train reliably. My options are:

1) Rebuild old gauge cluster myself and somehow convert speedo to work with new tranny (no clue where to start there)

2) Send out gauge cluster to someone for a new rebuild while maintaining stock look

3) Use new gauges in a custom faceplate I will manufacture (Autometer classic series or some other brand that looks like it belongs in truck. Wife hates the dakota digital retro 80's blue LED thing BTW)

What would ya'll suggest? Anybody have any pictures of conversions they have done? Prices or sources or contacts/companies to talk to very appreciated. Thanks
