Default help for dual master cylinder conversion 62 GMC

Hi guys

need some help on my power brake dual master cylinder conversion for 62 GMC drum front and rear

have used the Captains bracket, S10 booster and 68 chevy truck dual master

new master cyl. bench bleed, all lines are vacuumed bled

can not get much brake in the front at all, rears lock up easily

have read many different opinions on where to connect the front and rear brake lines

some say, front port ( furthest from firewall )of master should be for front brakes and closest for firewall should be rear, others say just the opposite

am very confused, does anyone have this set up using dual master and they work well?

what length of rod is needed for master cly to booster? and any chance my make up brake peddle rod ( peddle to booster) is not right length?

all help very much appreciated thanks JM
