Have been looking, off and on, for about three years for a 1228828 Information Display Module for my '89 Riviera and finally found one. I purchased a repaired unit form Rock Auto and they sent me a unit that was repaird by a company that I only know as "Standard". Could anyone tell me the rest of the company's name and where they are located? If I can find them and if the will repair my core I would like to keep it as a spare.
