Rocky Mountain Dashes??

The aluminum was nice, but hard for the average guy to weld. If I were to make one, I'd just use heavy gauge sheet metal. Make it as nice as possible with the welder and grinder, then finish it with some short strand glass-reinforced bondo, followed by regular creamy bondo, paint it and all is well.

Watch the depth of the speedo and tach. You have very little room to the steering column support. If you set the gauges too far back, they won't fit.
