Power Booster for Disc/Disc Conversion in '64 Impal

I have a '64 Impala w/factory power drum brakes. I want to convert to power 4-wheel disc brakes. I purchased an 8" dual diaphragm booster kit w/dual master cylinder from Performance Online to start the conversion. The booster/master cylinder measures 16.5 inches from the front of the master cylinder to the back of the mounting bracket (about 3" from the back of the alternator). In addition, the booster rests just above the engine dipstick, so close that it can't be pulled out. I heard that some company makes a streamline 9" single diaphragm booster that doesn't extend as far from the firewall. Does anyone out there know the particulars of this booster? Will a single diaphragm booster work in a disc/disc application? Has anyone successfully accomplished this conversion in a 63-64 Impala? Are pre-formed lines available for the dual master cylinder in a '64 Impala? I appreciate any help you can offer.

Hmmm ... I know that the hydroboost system from the same company is quite a bit more expensive, but it's quite small. It's also a very powerful system that works great on cammed-up engines with low vacuum.

Classic performance also makes an offset booster (over 2" and up 1") that may give you the clearance that you need.
