79-83 are compatible I think, I tried one off an IFS truck and it doesn't bolt up, I just removed it from the system completly.

i took mine off as well, with bigger tires it does stop a little better without it on, wears pads out quicker but at the time i was willing to replace pads more often then rearend cars on the street

Not as bad as my buddys 3rd gen, his tires were so bad in the rain that the ABS didnt even kick in at all, almost rear ended 2 cars in one trip on wet roads, one time we had to swerve into a turn lane to avoid someone! Then I realized he had 45psi in all four tires and dropped it down to 32psi and its been 100x better since, ride quality wise too.

My truck still locks the rear tires up with very little braking force so I gotta put a manual proportioning valve somewhere along the line.

i ditched the lspv as it had siezed and fitted a manual valve in the cab so it allows me to adjust it on the move. makes setting up alot easyer.
saves having to stop and get out and adjust
you can see it next to the transfer lever.

Brake prop.

I also got rid of the valve. I just put one from summit next to the MC. Once it was dialed in, I didn't feel the need to adjust it all the time. I have two settings, one for loaded and one when the truck is light. You can see it next to the MC.

with you guys that put the aftermarket prop valve in what did you do with the three way connector on the pass side frame rail......

also do you guys have metric valves becuase all i can seem to find is standard, i was hopen just to plop it between the lines on the above mentioned frame rail (instead of using two adaptors and two small peices of brake line)

I have a willwood prob valve i just havent installed it yet at the moment im running with only front brakes because i took the lspv off and just ran the fluid straight to the cylinders.....

T

Plug the T where the return line comes into it. I made a plug from the old line, by clipping the line about one inch abouve the fitting, crimping it then tig the end (I am cheap). Or you can by a metric to 1/8" pipe fitting and use a plug. My prop valve was also standard ( I cut my metric ends off my lines and double flared standard ends on), summit and even napa sell the adapters, for those that dont have the double flare tool. Don't quote me, but the metric end is M10x1.0.

You will notice a difference right away. Make sure you spend the time to dial it in.

I have a few question on doing this conv. So they maybe so dumb questions.

So you guys are puting a plug in the pass. side T and getting rid of the line that runs to the back valve on the frame rail? Then are you getting rid of the valve all together? Then do I put a manula PV on the line that goes stright back to the rear brakes?

Thanks for any help

They run $12.00/ea., male and female versions available. Handy for capping brake lines when you are working on the brakes or pulling an axle shaft. Also makes a great trail repair part if you rip a flex brake line on the trail. Just cap the hard line where the broken flex line attached to.
