I recently bought an adjustable knob type proportioning valve from Mustangs Unlimited for my 87 GT. When I went to install it, it doesn't want to fit in place of the female connector on the passenger side firewall. The distance between the fittings on the new valve is more than twice the distance than the female connector and trying to pry rigid brake lines is not something I like doing. Just wondering if anybody's valves went just fine and mine is the wrong size, or it is common to have to bend and pry to get the thing in.

I had to bend my lines to make room for mine as the valve is wider than the small junction that I removed from the brake lines. Did you also install your adapter fittings into the valve?
