Correct Temperature Sender For 67?

[1967RS/SS]

So, what is the correct temperature sender for a 1967 350 with factory console gauges?  Is it the threaded or push-on type?  Anyone have the original part number?Thanks...

This type, part number is 1513321 - see U17 A1 of the 67 AIM.  The harness clip pushes onto the top of the bayonet from the side:

For comparison, I believe this is the sending unit for cars w/o gauges, and used the same harness and clip:
