I hit the junkyard yesterday and found a 1977 Tach cluster.
$50 plus ride.
Top tab is broken off, housing is overall - brittle. Needles are sun faded. The "30" on the tach is also slightly faded more than the other numbers.
But, you can use some fiberglass repair stuff to fix any of the broken tabs. Pretty easy really.
Not tested.
Oil pressure line version.
So, with all that great news.....
Here it is.
