    Thanks guys
    It is the 15th car and since I am making it original, i think any original car is a trailer gueen or museum piece not a performance car.
    The car was original when I bought it 40 years ago.  
    Original was not performance. 
    It had a lot of shortcoming to drive fast.
    So original means drive slow and accept limitations.
    Poor AC
    Poor cooling
    Poor brakes
    Low horsepower 
    Limited tire traction
    Poor charging system 
    Vinyl seats
    Flexible body movement
    All the things I improved years ago to now go back to.

    > I agree with Mike to  point here. DOT 5 is silicone, and once it is switched to DOT 5, just figure that you have switched. As Mike has pointed out it is not easily reversable. It does work just fine for street driving use, you just won't have optimal braking, which on top of the stock Pantera Braking system could use other improvements to help things out, but is just fine for Sunday driving. DOT 5 does not absorb moisture, so your braking components will last a lifetime.

I would remove the supply line from each caliper to the hard lines, open the caliper bleeders fully, and blow a whole can of brake cleaner through each flex hose, into and through the caliper and out the bleeder into a catch bottle.
