Gauge pods anybody

I'd like to add 2 or 3 more gauges in my 68 Cuda but there is hardly any room under the dash and besides you can't see them while driving so I was thinking why not put them on the A pillar? So I looked all over Summit and Jegs and see they have pillar pods for all sorts of trucks and rice crap but of course nothing for an A-body, or any older car for that matter. Anybody ever try this and figure out some pods that might work? Would be nice to just screw something down and go but I'd even do some fabricating if I only knew where to start. Anybody done this or have any ideas?

BTW: 2-1/16" gauges is the size I'm thinking about using.
