It appears the replacement phono amp is the same size as yours. Have you asked if Simaudio can simply put the new phono amp face plate in silver on your unit?
I know for fact they have done this in the past.
Simaudio doesnt stock parts for discontinued produ
I tried to order a new face plate for my Simaudio LP5.3 phono amp. Wanted a silver one to match my silver power supply. I emailed Simaudio with the request. After 3 week they answered that they dont stock that part because the item was discontinued in 2010. Really, two years and they no longer stock parts.
I certainly know now what my next audio purchase will not be.
