I did a search for proportioning valve tool. The link below shows what it looks like.

DriveWerks.com - Proportion Valve Depressor

Make sure you truck even has this j block; some don't.

 

so this is what is all looks like right now. is there anywhere that i can buy the silver proportioning/combination valve and how much do you think it might cost? i think i might have striped out the back threads on the proportion/comb valve.

 

Threads or the flats on the nuts? You might need a line wrench to fit your B nut. You can start with bench bleeding the master cylinder, then reinstall it with the porportioning valve, then bleed to the rear, then front brakes.

 

I have line wrenches. but its not the nut its the threads inside the vavle.

 

Check salvage yards, or if you have a national parts store line available, check them for a new valve.
