Rear Brake Proportioning Valve

[GS guy]

I'd mount the prop valve as low as possible, then plumb a new short line to the rear T fitting. Then run a new slightly shorter (than stock) line to the front. If you're running a VW pedal assembly and mastercylinder, I'd try to stick with all VW stuff/metric fittings as much as possible. The more connections/adapters, the more chances of a leak!
I've seen generic bubble flare lines of many various lengths (but can't remember where at the moment?), so you could just make up your own system.

I'd also plan on one of these - pressure bleeder:

Too much fight'n and cuss'n to bleed a new (dry) system and get all the air out! BTDT!

Speaking from recent experience, if you just cut the stock VW line, you can re-flare it for the double-flare 1/8th". I can't guarantee this, but I think if you get a Wilwood brake proportioning valve and a couple of nipples, you can just cut out the stock line where you want the valve, double-flare the ends, and bolt that up to the valve. Then you'll have hybrid lines, half bubble metric, half 1/8th NPT. I used the stock VW lines to tie into the steel braided cables that are meant for VW Jetta, and the other end I did to attach to a standard T. The only think that might be a problem for you is that I would want my valve within arms reach, and unless you can pull any excess, the valve would then be low where the stock line runs.

That is what I am going to do. I just bought a tool (10mmx1.0)for this

Summit has real nice Tilton brake bias proportioning valves in stock metric 10mmx1.0 size). I got one of these:

That looks great Wally, and easy to adjust on the fly. I always wonder how those longer levers work in daily drivers, if they get caught on stuff or not, but there's no denying the ease under way!

Good point about the lever, but I think they also have one with a knob if that concerns you.
This one is NOT going into my daily driver

Mine will be a fun weekend thing, but I got the knob myself!

I installed it. Best place was this as I can reach it from the drivers side and it doesn't touch my leg. It not in the way for a passenger either now
