Greenhoe is probably the best, also most expensive. I just bought a complete set up for $365.00 for my 69 Z/28. It is awful close, if not exact to a 69 set up until you start reading dates and numbers. I bought a repro deep grove pulley and cleaned it up and it looks great to display with my day-2 Z. It really does look very nice with not much invested. Has the white fan and spins freely. You are right mix and match on e-bay for this junk anyhow. Sam
