Freds 73 Scamp restore on a budget

Morning Charlie was going to use the ones off my 340 and just clean them up for now.
I was looking at a new alternator a one wire hook up but don't know how to hook it up to the amp gauge. Also a new set of headers I have a set of short tube ones from headmen but not going to use them. Thinking TTI.
TTI would be nice. I've been hearing about remflex exhaust gaskets too. It's all a tough pill to swallow but probable only got to swallow it once.
