Load Sensing Proportioning Valve (LSPV) different part numbers

[MattEnTheHat]

So my LSPV is rusted to hell, leaking slightly, and has a torn boot, so I want to replace the whole thing. Toyota claims that both part numbers 47910-35220 and 47910-26111 are direct replacements. Just curious if anyone has any idea what the difference is?

Aside from 35220 having a blue finish and 26111 having a black finish and being $50 cheaper, they seem identical to me. Does a higher part number imply newer/redesigned/improved or anything?

I was able to figure it out (or at least which is intended for my truck - still can't tell what the actual difference is). For anyone stumbling onto this, this site is an incredible resource: toyota-usa.epc-data.com

that's handy to know.
I just eliminated mine to get full power to rear brakes always.

Delete it and put in a in line adjustable proportion valve in line.
