what does your proportioning valve look like that you have now?

[rebel1001]

its a metering block.

[sleepychallenger]

if im not mistaken, you should have a proportioning valve.

[Chryco Psycho]

the proportioning valve should be under the firewall along the frame rail in the rear brake line on a factory disc brake car
