Brake Booster riddle - can you solve it?

[HiboyGal]

You all know I love my old school buick finned drums and I'll be darn if I am going to take them off and put disk brakes in the their place!!

You also know they really don't break worth a you-know-what. I know I can't expect miracles from adding a power booster but I was told a power booster would improve break performance by about 30% or more. Good enough for me! 30% more is more than deedlee squat. Sign me up!

NOW HERE IS THE RIDDLE PART:

I have weird custom cross members on my frame that are (SEE PHOTO BELOW) in the way and unless we cut through the frame we cannot fit a conventional power booster/master cylinder unit.

So the next best thing is a remote booster I could shlap a bit further down (on the other side of the cross member, or anywhere else under my frame). I have room, just not enough room to fit the current lareger round remote boosters found on the market today... Unless you guys know of a smaller booster on the market I don't know about (send link).

ANY SUGGESTIONS?
