Gauges RD 350

[Salty55]

All, after advice on a set of gauges for my RD 350 project. After a “Smith’s” simple look in about a 60mm (both) or a larger speedo say around 80mm with a matching smaller taco. Prefer a chrome or polished ally look and obviously needs to match standard speedo and taco cables for the 1973 RD. THoughts?
