Gauge problem

[the idiocracy]

Anyone know of a common way to adapt 3-3/8" speedo and tach to the factory 5" holes? I am putting a boost gauge in the center hole and want to put a 6 gauge kit in using the other holes.

Right now my plan is to fill the 5" hole with black tinted epoxy resin, but I feel like this might not be a long term solution.

It would be good to see pictures of what you're working with.

I have a set of used autometer gauges that have been sitting on a shelf for awhile. I'd like to try using a glovebox door to mount them, I've seen some nice examples.

But, if you want to go the route that you suggest, you might be able to find - or make - some sort of bezel for the gauges that looks good and allows them to sit in there nicely. Some pics would be great.
