I recently got an oil temperature gauge and vacuum gauge from ebay that fit in there, but you should be able to fit other 52mm gauges too.
If you're on ftooc.org check out the oil filter adapter block thread, they get into talking about gauges there. Greengauges look a good match to the stock dials.
