Pre'65 Chryslers had pushbuttons, so no 'sticks' sticking out columns and such.
1966 was the first year (Budd) discbrakes were optionally available on Chryslers.

Today I've located an alum. prop. valve I had bought once, along with a 'linelock'-installation kit from Summit. This kit has 4 or 5 different lengths of brakelines in it, and also a bunch of various sized fittings.
I would stronly suggest buying such a kit if you're doing a discbrake conversion, as it makes reconnecting the brakelines a snatch.
No flaring is needed as the brakelines come with fittings pre-installed.
