Difference in gauges/senders. Quick note:
Some have asked if you can use the older M series gauges (metal connectors) on the newer M series vehicles (rubber connectors), and visa versa.
The answer is YES, but only for the oil senders and oil gauges. There is no difference between the early gauges/senders and the newer gauges/senders aside from the difference in connectors.
The answer is also NO. This is for the water temp senders and gauges. Aside from having either a metal or rubber connector, the Military wanted TWO types of water senders/gauges. It appears the early gauges (metal connectors) had a temperature range of 60-260 degrees. When the rubber connectors were standardized, the Military went to gauges with a 120-240 degree range.
Rule of thumb. When getting a replacement oil sender, make sure it reads "60lbs" or "120lbs", whatever you need. When getting a replacement water sender, your stuck using the one with the proper connector for your gauge.
I ran into this issue myself back when I was putting 24V stuff on a 455 Oldsmobile engine. I purchased 24V senders off a Multifuel engine. They had rubber shells but my gauges had metal shells. I just made adapters, trouble is the water sender was for the newer 120-240 gauge, my truck being an older M211 had the 60-260 gauge.
Just clearing up any confusion for those new to M series stuff..
