It appears to be a CNC aluminum master cyl. used in sprint cars etc and sold (Hall?) in the LA area for Panteras. One of the few that are a bolt-on since clutch master bolt spacing on Panteras is tighter than normal so cheaper Girlings etc won't fit directly.
I notice your brake booster on this car has the reverse vacuum line setup. Most Panteras have the vacuum line going up thru the same hole in the floor as the clutch master line. Has the booster ever been replaced? Just curious- the placement of the line is only important if you carry wide stuff in the frt. trunk. I needed such a booster when trying to fit a high-pressure 4" x 16" spare tire/wheel in a front trunk. Boosters are symmetrical & when rebuilt, can be assembled with the line in any of several positions.
Yes Bossman, the master (whole car) was from Hall. I looked at early restoration/build photos, and I see two holes are present in the front trunk floor while the car was being built, but I don't know if it was added or the car was like that from start.
Now on to the slave: I picked up my long throw slave, and the small rod inside is longer than my current unit by about 1/2 inch. So in order for it to fit into the car, I would have to adjust the clutch arm way back to the rear of the car, and going that far just seems odd, and leaving huge room for the small arm adjusting screw (at least 1 & 1/2 inch). The photo shows the size of the rod on my old unit next to the new unit with both screws screwed in all the way. I could cut the bolt on the new unit to allow it to go in farther, but that still wouldn't create enough room (maybe would if I totally eliminated the nut on the rod as well). I think I may just chrome my old rod and bolt and then use this in the new unit. But this made me think,is the rod length the only difference in a long throw slave from a regular unit? That wouldn't make sense because just a longer rod wouldn't create any "longer" throw from starting point to extention. My old slave unit main housing is almost identical to the new long throw, so maybe I had an aliminum long throw in there to begin with, and only difference is this longer rod.
