To add to my earlier = instructions on making your own guage cluster. I filled the void between the three = pvc "tubes" with 5-minute epoxy, but only after positioning some = threaded rod in the angled end for use as a mounting device. Then I drilled = a hole in the dash just to the left of the speaker perforation for a location = for the cluster.

I'll try to get a picture, = or at least a diagram for someone who want to attempt making one of these = things. I did it in a couple of nights, without too much trouble.
