installing a new distributor and 1 wire alt.

I bypassed the ammeter years ago, I have #2 welding ground cable as my battery lead from battery to master switch and then to starter. I have #4 lead from start relay to starter post. The rest I will have to dig in and see what I cobbled together 10 yrs ago. I did add autometer gauges to the stock dash bezel and used an painless gauge harness. Thanks for the info. What brand 4 post master switch do you use?
