I'm in Cupertino California, near San Jose and would love to meet up with a knowledgable Diesel guy who is familiar with 1997 K3500 6.5 to show me a few things and suggest a few things and do some things to my mostly stock truck to improve overall performance and be up to date on maintenance. I'll pay a fair price and tip you in Wine as I work at a winery. The last thing I'd want to do is drop it at a dealership. Can email direct dude@websitedude.com
