You could take out the panel and mount something like an early Pacer one there, they have rounded edges and a lot lower. I doubt there'd be any paperwork needed because it was an earlier Piper panel, factory fit. Still enough room for ASI, ALT, T+B, Tacho and combination oil pressure/oil temp. Those along with a bouncy mag compass on the dash and your set.
Colt is a very appealing aircraft, basic flying at it's best.
We had a Tri, was a lovely little machine.
