brake conversion question
Hi all, I am comverting my 74 F100 4x4 from drum to front disc brakes, and thought I had it all worked out, using all parts from a 78. Here is my issue: the old metering block had 4 lines total, two inlet, and front and rear outlet. I purchased a new OE prop valve from J.B.G. and it has two inlet, one rear, and two front outlets. Yet the lines I bought have left and right on the diff, with one flex line that runs to the frame/ prop valve. What am I mising here? is there a two to one distribution block between these lines? or do i just block off one of the ports to the front?
I dont have a donor, or access to a 78/78 to look at, so I am kinda lost here.
any help would make my day MUCH better...! Thanks!

That's pretty expensive at JBG,
I found this one
http://www.inlinetube.com/Prop%20Valves/VFL101.htm
plus another at another FTE sponsor NPD for $165.00.
It seems they are finally making them (the stock type) available.
It's too bad they are so darn expensive
Here's an illustration of an 78 BPPV.

Jeff's bronco was also 165.00..... ( thought they were a sponser..?? my bad for not double checking )
I saw the aftermarket one, but had an uneasy feeling about it, so thought it would be safest to stick with OE.
Thanks for the diagram!

JBG is a sponsor 
I was really just pointing out that more people have the STOCK units now and prices vary.
