Yes, you have two ways to go with their kits...
One is to keep the under body location and install the booster/master in that location to keep your original pedal "thru the floor"
or,
convert to a hanging pedal with the power master/booster on the firewall.
Using this one you cut out the old stamped sheet metal dashboard brace and
replace it with their 3/16" steel brace assembly that the booster then bolts directly to thru the firewall. Since I went with a new tilt column I decided I'd prefer this set up. It's quite stout.
Hope this helps
