Re: Coolant Temp Gauge - What makes it work?

Thanks to both of you for responding. My truck is an 86 K30.

I located a NOS unit on ebay: http://www.ebay.com/itm/NEW-ACDelco-...f7731b&vxp=mtr

My truck takes the 1/2", I am guessing since its a big block. Will this be the proper unit to order? Or does a reproduction company make a better unit since there was some debate previously about even the GM/Delco ones being more universal since they haven't been made for a long time.

Suggestions?
