Hi guys.. I have contacted a few local auto electricians (regarding elctrical problems with my GTS dash..) and one of them said that Holden used different guages between HZ-WB GTS dashes. They then went on to tell me that I would have to replace the insides of my tacho to suit electronic ignition (because HZ had points, and the tacho is set up/built to run on those..)

My question is, do I really have to replace the insides of the tacho to suit the electronic ignition??? and did they actually use different guages between HZ-WB??

Ohh, and if they do have different brands of guages, do they have to be all the same brand or can they interchange??

Thnaks for the help..
