brake install, double check me !!

[skip99]

hey guys, just spent waaayyy too much time on this. and would like double checked ! read a lot of old posts and builds and got this far..

it's a firewall mounted 8" booster, disc. drum. 16" pedal. so , I drilled a hole 3.5" down from the pivot to attach the rod, which gives me a 4.5 ratio, right? and this seem to be the norm for boosted brakes?

manuals run from 5 to 7 ratio , I think.

I have 5" of pedal to floor travel, and 1 1/4 " of rod travel in master cyl.
look ok?
thanks.
