Yes I think I've seen them mate, are you talking about the replica ones?
I've pretty much decided to getthe Defi Din triple cluster like you have mentioned
Neat, reliable and will bolt straight In to factory dash
Inc 1 pressure and 2 temp gauges, so fuel pressure and water/oil temp is what I'll go with as the factory water temp gauge is shit (killed my first engine) and low fuel pressure ( killed my last engine)
I was going to go oil pressure as well but the factory gauge is reading close enough for my liking
Reliabilty was main main concern and I don't think you can go past the Defi's
