Temporary air gauge and switch. Where to find?

[jimmydean]

I bought my gauges off ebay for $6 each (dual needle 150psi). I was going to run the gauges Porterbuilt posted a while back because they are small and he said that was all he used. They were also somewhat cheap, like $20 or something and 1 5/8" in size if I recall.

You can get a switch at Autozone for like $4.

Got any progress pics? It's looking good so far.
