Here's my Dream

I have no desire to restore this bike (at least not any time soon). I really want to preserve it and ride it. It's only original once! I got it running and enjoyed it for a while, but I struggled with the common issue of the float adjustment and gas pouring out the overflow. It left me stranded last fall and I'm just getting back to getting it going again. Below is a list of what's been done so far.
Rebuilt & cleaned the carb
De-rusted the gas tank. I used the muriatic acid method
New air filter
New battery
New fuel lines
Working on correct mufflers. I bought a "pair" of used original mufflers, but ended up with 2 lefts. I've been riding with some generic slip ons that my Dad modified to get by. Once I get a decent right side muffler, I'll be pretty close to running again.
I think that I need a new left side header. The pipe does not quite reach my original muffler.

The left header is longer than the right correct?
Also, should there be a seal/ gasket between the header and muffler?
Here's what needs to be done...
Right side muffler
Left side header
Air hose from carb to air cleaner
Fix broken speedo
Fix broken headlight dimmer switch
Fix funky ignition switch (needs new lock mechanism. Anything can turn it)
Add turn signals (as close to original vintage as possible)
Add rear luggage rack or Buco bags
Fix horn
I look forward to any help I can get!
Thanks!
