In this case I recommend side stepping the Morgan parts specialists and going straight to the source, CAI have supplied Morgan with all their gauge sets for some 30 years or more, and continue to do so to this day. Actually, as CAI took over Smiths many years ago, you could easily argue the relationship with Morgan stretches way further back than that as Smiths were supplying Pickersleigh Rd with instruments from the early 1950's.
https://www.smiths-instruments.co.uk/morgan-motor-company-and-smiths/Being the original manufacturer, CAI offer everything from a small gauge repair to a full rebuild, they also offer a custom gauge face service.
I had an AFR gauge refaced by CAI to match my original TVR Chimaera gauge set, TVR also used CAI for years. I replaced the clock with my new and now perfectly matching gauge that I then connected to my Canems standalone ECU to give me live air fuel ratios. Because CAI made the original gauge set for my 1996 Chimaera, the cream pantone match was identical, and with a correct matching brushed/satin bezel installed my AFR gauge looked like TVR had fitted it from new
As you're looking for cream faces, why not go with the 80th anniversary Morgan 4/4 gauge faces? Given these were created by CAI originally I'm sure they still hold the artwork, so it'll be no more complicated than pulling the file up and sending it to their gauge face printer.
Actually, as your Plus 4 will be a direct injection 2015 model your gauge set will be slightly different to the 4/4 and earlier port injection Duratec Plus 4, but CAI will hold the artwork file for the later Plus 4 gauges too, so when they initiate the print run they'd simply produce in cream rather than the original black.
I would also have them fit your new cream faces to your gauge set, it's a fiddly job and you really need a proper bezel rolling tool to avoid buckling the soft thin bezels.
Hope this helps?
Dave.
