47-55.1 rear brake line routing

[nvrdone]

I need to re route the rear brake line on my '49 3100. so far I plan on running the line from the m/c down the left frame rail. im not sure where to end it & how to route the hose to the rear axle. the axle is a 12 bolt out of a c10 & the lines to the drums come up to a connection at the top of the diff. should I end the line on the frame even with the center line of the axle & use a hose over to the diff? or should I route the line across the center of the rear crossmember & run a hose in a loop to the diff?
any ideas & pictures would be appreciated
thanks
