Help! Engine instrument multiplexer obsoleted

[DougW]

My Coach is a 2001 Newmar Dutch Star, diesel pusher on a Spartan Chassis. Specific model is DSDP 3891.
My concern is the multiplexing box that manages all of the engine instruments. Should it fail, all engine instruments fail. Spartan 'obsoleted' this box a number of years ago and there is no alternative part that can be used. Spartan tells me this particular box was used from 1995 to 2003 on the chassis' they provided to RV manufacturers.
The Spartan Part# is 0920-NN1-013 and the Stewart Warner part# is 988H-1.
My question is "has anyone been faced with the failure of this box and what was the resolution?"
Thanks for any insights/thoughts.

Google search on the part # found a used one...

Spartan sells all of their discontinued parts to this company https://www.vpartsinc.com/. I needed a fuel gauge sending unit and couldn't find one anywhere and Spartan told me it's discontinued. At the Tampa RV Supershow in Jan 2018 I went to the Spartan display and talked to the Parts Manager. I told him I couldn't find one and he checked and said there is a couple over at Vintage Parts (address above). Sure enough there was - they were not cheap but I bought one. If you have the Spartan part # contact them through their site - their number was different than what Spartan gave me. Worth a shot. Good luck.
