Smiths Gauge Replacement Glass Replace damaged or missing flat glass in Smiths speedometers, tachometers and auxiliary gauges used across many British classic cars and motorcycles. Our clear round replacement glass is precision-cut in the UK and is suitable for restoration work where the original part is unavailable. The current range uses 2mm flat glass, available in 1mm diameter increments. Front and back edges are wet-finished to produce a smooth, clean component ready for careful installation into the original bezel or instrument housing. Smiths instruments vary by model and age, so measure the original glass and housing carefully before selecting a diameter.
