Brake servo check valve wanted

[nozamaman]

I am trying to source for the brake servo the check valve for a 1970 145 the servo is the early one up to chassis numbers 178959 on 142s to 194139 on 144 and 61599 on 145s, the Volvo Part number 678407-8
the check valve is white Nylon and has three lugs at 120 degrees to fit into a matched opening in the servo housing. Later servos had a push fit check valve and are similar to later Volvo servos. the distinguishing feature of the servo is that it extends from the brake pedal forwards on the offside of the car (RHD) with the brake master cylinder in front of the servo body and the master cylinder is near the front panel almost up to beside the radiator,unlike the later 140 servos which the brake pedal movement is transfered across the firewall to the nearside (RHD) any help with sourcing this would be appreciated.

They say a picture says a 1000 words, well this is my 1970 145's servo (no rude comments about the rust thanks!)
I didn't want to remove the valve for fear of breaking it! It is very cold out there today!
I presume this is the type of servo in question?

No problem! Its good to hear of another 1970 145 survivor, and local too!

The valve is only a tight push fit. BTW why do you want to replace it? Prise it out, it won't break unless you'r ham fisted. Just suck the pipe conection and you should hear it click back and forward. If you think you'r losing vac' it's usually where it plugs into the servo. A bit of silicon will seal it. It did with mine.
