Brakes problem
1989 Chevy Silverado V8 Four Wheel Drive Automatic

I have a proportioning valve that has a brake line inlet that has a stripped thread and cannot be rethreaded. So I have obtained a second hand one but it is different in appearance.

The one that came out of the truck has a number on it FF 21 KH 1509 and has two valves at each end and the second hand one has numbers FD 22 KH 2997 on it and only has one valve at one end.

Ok with it looking different I would say no it probably isn't the same. Also you mention on truck has 2 and the other has one this is also going to make it different. So tell me what year is the used one out of?

The vehicle dismantler does not know what year the item was remove from and has told me it is out of K/C Series 1988 to 1990 model. Thats all I could get out of him.
The main question is will the Valve with the FD on it do the job.

If they look different as you are discribing then no they will not interchange.
