Hi there so I recently purchased a QP 9" with disc brakes for my 83 Elko and have it all setup now except am having problems bleeding the brakes I should note that I had to change the brake line that runs from front to rear T during rearend swap. I have some pedal but its really not much compared to what I had with my drum brakes setup. I realize now at the minimum i need to get a new proportioning valve for disc-disc setup, but is there anything else I should cover while I'm at it? I've also read that you can simply modify the stock disc-drum prop. valve for disc-disc just by removing the small rubber piston from the isolation valve. Can anyone actually confirm/deny this? The instructions for it are here:

Not trying to be cheap, prop. valves aren't crazy expensive, but if its true I wouldn't mind doing that just to get it back on the road asap! I know there's a bunch of posts about converting to disc disc setups but I haven't seen much about modifying current prop. valves for it, but if there is could someone please drop a link for it!
Thanks!
