my new dash
the tach and speedo are 3 3/8" and the other gauges are 2" - actually about 2 1/4 but their listed as 2". I really like the redline cluster- a little expensive but no other choices really. It wouldn't be possible to put a 5" tach in there in fact I was starting to sweat getting all those gauges in there.I wanted the tach and speedo on one side and the other four on the other side but it wasn't possible.
