I couldnt go the welding route since I have cork and leather like material glued onto the dash. It would have burnt up. I couldn't see any other option (unless I redid the intire dash) except to remove 4 small holes from the front side of the dash (the cork and leather) and carfully center punch, drill, and bolt it on like john streak mentioned.
It turned out ok. Im not 100% happy with it. But I dont think I had any other choice.

O yea, and as far as glueing it goes, Im running a YJ tub, with CJ dash and duct system, and YJ defrost. So things are very tight behind the cluster. There is no way glue would hold this one in, with the speedo cable pulling it down against the defrost duct!
