I got mine from diesel injection service in Lubbock, Tx. I got a 0-50 psi Isspro boost gauge, and a Isspro analog pyrometer for something like $175. 00 delivered.
I like the gauges themselves, but the lighting sucks big time. I wrote to them about 4 months ago to get a brighter light part #,(everyone apparently has brighter lights, but no bulb number??) but still dont have a reply.
I put these in a pillar mount, but it was extra. I forget how much $$$.
