New 1964 owner with many questions

9 drums suck but they work, but barely in my opinion. manual gives a better feel, power is not really necessary
if you got the money, prebent lines are 'drop in' flaring brake lines requires the tools and get the softer brake line, stainless wont flare easily with cheap flare tools
only source for stainless is used, lots of guys here sell this stuff.
electronic ignition was stock so its easy to find the stuff used cheap, like $20 for an electronic distributor and another $10 for the ECU
complete exhaust can be found new, even manifolds. Upgrade to 2.25 head pipe.
