I've searched these forums for an answer - no joy.

I have a '66 fastback. The car was manufactured with drum brakes all around. The PO replaced the front drums with factory 4-piston discs.

I have the Kelsey-Hayes proportioning valve. I understand it mounts to the fender apron, between the driver's shock tower and the firewall.

For the exact location, the PO suggested that there is a "nub", or depression in the fender apron. I think I've found one by reaching under the fender and feeling the apron. I'm assuming that this depression is where I would drill a hole.

Can someone confirm with measurements/photos/other info that this is the correct location? I'd like to attach the prop valve as close as possible to the factory location.

Thanks much.

You should find two. One will be drilled the size of a small post on the back side of your proportioning valve; and the other the size of the stubby little screw that bolts through the inner panel from the outside to secure the valve to the inner fender apron. they're about 3-4 inches back from the shock tower, about the same distance up from the frame rail if memory serves correct.

I don't have any good photos of where I mounted my prop valve, its hard to see in there.
But, I can say that I was able to mount it basically in the same spot. I believe I was able to use one of the original holes as well.

Here's the best I could come up with my "very cheap" digital camera. It doesn't like low light photos..

I believe the original location is down and to the rear from there.

Thank you, everyone. I'll inspect that area much more closely and, if necessary, ask for more guidance.
