Man, you may want to see what those run for on eBay first. I about crapped when I saw how expensive the vacuum gauges were, when you guys were posting pics.. I have one, and was gonna post a pic of it. I couldn't find it though. Its SOMEWHERE in my garage..... LolI do have an old prechinesium SW tach it only goes to 5K, but for under hood stuff would work fine. Hmmmmm
Honestly, I never had either, until Honkey Kong started talking about his timing light. That IS what drove me to put in a underhood run/kill switch though. Got tired of the PITA jumping in and out to start the thing, when I was working on it.Never thought about a tach under the hood, this would eliminate my constant walking back and forth.
