Temperature Gauge/Sender matching

[cowtown]

Car: '75 911S
Engine: '77 930

Hi, can anyone tell me:

1) What is the part number of the temperature sender that I need to work with a 1975 gauge?

2)I've pulled out the little pointer/scale assembly from the gauge, but I only see these numbers: "107 126". It reads from 0-300F. Is this a stock '75 gauge? Where do I find the part number on a 1975 temperature gauge?


I've got sender #911.906.112.00 in the engine right now, but I think the '77 Turbos had a non-numeric gauge face...
