[Roadsters] early gauges

[Tim]

Is there a write up somewhere on how to remove the bezel and glass from the early gauges? I recently aquired a complete flat dash and want to have all the bezels done. Or can someone please tell me?

Also, is there a (comlete) write up somewhere on how to test all the guages? Or, again, can someone please tell me?

Since I am too tall to ever be able to safely drive a low windscreen Roadster (and I prefer that look), I am going to come as clase as I can by putting a flat dash in my 70 1600. 

TIA

Tim
