Hi,
I’ve had a lot of the same issues with my stock ‘73 setup… as for the thermostat control for the preheat flap 113-129-828A, replacement on that is +$100… which is insane… I stumbled across a Volvo part for $16 that I believe does the same and looks almost identical. volvo #9209888 . Hope all that helps if needed. I’m going to order one and report back…

Great find
The valves are adjustable, so even if they are not 100% correct, one could adjust them to give the results one needs. FWIW, running a progressive and wanting all the heat I can get, I adjusted the VW valve to give about 20°F hotter temperatures. |

Good to know they are adjustable. Learn something new every day. Just did a top end rebuild on an engine after dropping an exhaust valve on another engine… so just been going through all of the vac parts and came across this thread.

Fits perfect. Not sure how to test what temp it opens at though. Any ideas are appreciated

I'd attach a hose to whatever port is closed when cold and immerse it in a water bath with a thermometer in it, gently blow on the hose, when it starts making bubbles read the thermometer.
