Rob, I'm using the SW gauges also. Just order the dash with out holes and use a fly cutter to drill the holes. It's pretty easy.
That being said I don't recommend the SW gauges. Maybe I just got some bad ones but they don't seem very accurate. And I had trouble with some of them. Granted I bought them "used" but they were supposedly never actually run. I had to replace the tach and oil pressure and I'm pretty sure the oil temp is not working. The tach is SLOW. My rev limiter is set at 5500 rpm and according to the tach it's kicking in at 5000 rpm. I'm betting the tach is either off or too slow to keep up. I'd get Autometers if I had it to do over again (I may get to do it again).
Just my thoughts.
