Hydroboost Installation Q?

[Bigdav160]

Has anyone mounted a hydroboost unit to the factory vacuum booster bracket?

I have seen CaptainFabs brackets that eliminate that feature and mount the hydroboost unit to the firewall.

I've also heard concerns that the pedal is touchy after conversion (mounted to firewall). Sometimes attributed to incorrect pedal ratio(?) and nothing to do with CaptainFab's brackets.

I noticed the factory power booster bracket has a small amount of lever ratio built into it.

It also looks like mounting the hydroboost would be a snap as it is almost the same length as my 3/4ton vacuum booster and the mounting holes are nearly the same.
