I finished up a few more combo gauges after the holidays and I'm planning to build one more batch of these in April. My son will be home for spring break at the end of March so I'll have him make the parts I need. This will likely be the last batch of these for the year. My son took an out-of-state internship for the summer so it's doubtful he'll be home before starting the next school year. If you're interested in a quad or triple gauge, fill out the Google form and I'll get you an estimate. I'll need to nail down the details by the second week in March to be able to get it into this next batch.
