I'm about embark on upgrading my '55 1st to dual master cylinder (from original single). Have most everything needed including the dual-MC adapter bracket.

The brakes will remain all drums, with new wheel cylinders and hoses onto the front only -- rear axle assembly is a positrac from '71 Blazer and brakes & lines seem ok there.

I'm going to yank all the front brake lines out and just leave the rear lines including the very back axle 'tee'.

I figure the Front port of the MC will go to the rebuilt front brakes & new hoses.
The Back port of the MC will go to the rear brakes via a 3/16" union that replaces the 1/4"x3/16" 'tee' at the right side frame rail. [That was via the tranny cross member]

But I can't seem to wrap my head around how to effectively plumb in the new fronts off the MC front port.

So, what I need before starting this project are some brake lines routing details from those of you who have done this project before.

A diagram and/or some photos would really help if you have any -- thanks.
