[Green Machine 79]

Thanks Tiger Joe! I'll look into that.. I ordered new light sockets anyway so I'll be back into it soon.

In the meantime, I got a mech gauge from Napa today. Got it in and took a drive. Gauge read right at 185 both in town and on highway. It went up to 190 once I pulled back in to the driveway and let it idle. So I think I'm good to go for now.

I read online earlier today that the sending units with the nail heads were built for gauges while the ones with 'tab' connecters are meant for switches. That doesn't explain why my only stated options according to part lists have tab connecters. But I plan to take hatzie's suggestion and contact 'Letric Limited'.

Thanks again everyone!
