Proportioning valve swaps

While doing some break work on my CJ I noticed that the Proportioning valve is spitting brake fluid. Mine has drums all the way around. Can I use the Proportioning valve that is for models with front discs and rear drums?

I think you are going to have to stick with one with drums on both axles. Front disk brakes require different pressure and volume than drums do so I am pretty sure that would require a different valve.
