The plan is to mount a modern booster and dual circuit master under the floor like hotrodders do. In order to achieve this, I need the rod going towards the back of the car, not the front.

This was discussed a few years ago during some of the BTV replacement threads but don't recall any posts of someone ever trying it. In addition to modifying the original pedal there was also some thought of using a modern weld or bolt in hot rodder pedal and booster assy under the car instead of trying to modify or source another pedal and then still need to do the other mods.http://www.abspowerbrake.com/maincatalog_frameset038.html

In addition to TL clearance issues on 55-6 models another issue that caused some concern with the under floor setup is that by the time the assy is put together most of the modern boosters capable of stopping Packard's weight will have a height of 8" or more. The 51 and later frame rails are only around 5 1/2 or 6" high so unless some accommodation is made in the floor pan to accommodate the diameter and could be hidden under the seat it would mean a portion of the booster will hang under the frame unprotected and vulnerable to road debris. On that ABS page there is a mini booster unit at 6" but the question on that unit was the small booster strong enough to stop a 2 ton car.
