[urq] Compact Brake Booster

[AF]

Does anyone know what the smallest most compact (least depth) vacuum booster
will bolt up to an UrQ? I'm currently using a 200 20v short master cylinder
with the 1-inch piston bores and a 4000Q booster if that matters, but I
would like to gain another inch or two between the engine and the master
cylinder in my V8 swap. Any thoughts are greatly appreciated.
