FYI

I have finished installing a dual master cyl on my '47 Hudson truck using a '37 pedal assy as a template.



I used a 1/4" pc of mild steel

from Lowes about 2" wider than orig master cyl bracket bolted

to the 3 bolt pedal assy as an adaptor then drilled and taped two more outboard bolts to hold the dual cyl. It required countersinking all the holes flush then use 'button head' bolts.



I utilized the dual cyl pushrod (supplied with cyl) by threading to insert into the stock clevis to adj free play.



The nice feature (besides updating to todays safety) is that all the emergency linkage remains intact and the clutch pedal is still usable if have a standard trans....



Then needed only split the brake lines at their Tee, running the front brakes into the larger chamber and the rear brakes into the smaller chamber..



I utilized a Ford Torino 'manual drum brake' master cyl # 10=1519 because of using drum brakes. However, if using Disc simply get the 'Disc' Master cyl because of residual valve pressure.



Only drawback is re filling 'might' require a long funnel but how often is that needed...



Suprisingly, It was one of the more simpler things Ive done in my retro work...I have a couple pictures if interested, but uncertain on post process..
