New 1964 owner with many questions

Welcome.
Cool car; post pics if you can.

Questions:
1. No power drum brakes are they adequate for a daily driver?
- Barely, you can get by if you stay alert and anticipate the awful drivers and people texting. And an upgrade to front disc brakes requires at least 14” wheels from your 13” ones.

2. Is it worth buying JEGS steel brake lines vs making your own (my thought is I don’t have to buy tools )
- Im Not sure.

3. Is there any source to buy stainless trims, taillights, etc.
- only used, this is the big frustration with all these pre-‘66 A-body cars, good exterior trim is difficult to obtain and there aren’t too many reproduction pieces available

4. Is Borg Warner electronic ignition kit EI-6 worth buying? Is there better options without spending hundreds of dollars
- looks of good affordable alternatives

5. Does anyone makes complete exhaust for slant 6?
-yes:
