GMC OEM Clock

[jbgroby]

My brother and I started the wiring process on Saturday. HE gave me enough pointers to be able to do the dash myself with him as a life line via cell. One of the things we took a look at was seeing IF the 12 v clock would work. We are using a trickle charger to get the 12v power, but we were wondering IF we had it hooked right neg ground to the metal body and the pos. clamp in the center post?

Along those lines does anyone have a link to a company that restores automotive clocks? I have not serched Hemming as of yet, I'll probaly get a faster answer right here.

Thanks
