Default modulator valve question

Where can I find a modulator valve for an original automatic 65 GTO?

RockAuto says they have them. Fram FM2310 replaces GM part numbers 1361577, 1365187, 1367032, 1367034, 1379566, 1394525, 1394526, 1394527, 3027223, 3963812, 3963820,

1966 Pontiac Chassis Parts Book says the GM number to use is 1361577, 1365187 or 1367032 depending on A.C, or not.

Default OEM Modulator

Here’s a Factory NOS #1365187 modulator.

This is the same unit that is on my ‘65 Automatic.

It is the same mod as used in the T350/400. Aftermarket units are smaller & adjustable.
