Did Chevrolet hire all those out of work midgets from The Wizard of Oz to install the instrument panels on AD trucks? It's ridiculous!

I cannot get the two nuts on the driver side off the back of the gauge. I can't even seem to get a wrench or socket on them. I can barely get my head in there to even see them.

I'm not fat (170) and I'm fairly flexible. I can't seem to get into a position to get a tool on those two nuts. The other two were no trouble.

I'd rather not drop the steering column or open up any other can of worms to get this gauge out. Anything I haven't thought of?

Also when it's time to go back in with a replacement, would push nuts work? I dread having to figure out how to get nuts back on those two studs.
