Yet another Proportioning Valve?
 

Is there a difference between a 3/4T & 1/2T Proportioning Valve?

In my assembly manual, it shows 2 different brake line routings from the ms to the prop valve, but does not mention if the valve itself is different or not.

Would that only depend on if you got a 1/2T ms or a 3/4T ms, would those lines run different? The one I have came off a working 71 3/4T and the valve looks the same as one from a 1/2T.

Hope that isn't too confusing. I need to know this before bleeding the new disk brake swap.

Here's a picture of the valve I'm using.

Proportioning valves are the same. The brake line routing from the master to the valve are just the opposite on 3/4's & 1/2's. I just went through this with my 69 3/4 disk swap.
