i just went through this for my 98 3500 express for a temp gauge that was broken... They are vdo gauges but are no longer made, i was lucky to find a replacement on ebay for mine.. These screw in the dash panel and are flush with no bezel. I read somewhere that there is a company in ft lautherdale that fixes these... good luck!
I just used Lauderdale Speedometer over the winter to fix and calibrate my VDO temp gauges that are no longer available. They were great to work with and the gauges look like new. I can't vouch for the repair since my boat is not in the water yet but based on the different techs I spoke to they seemed extremely knowledgeable.
