I'd like to add a note of agreement about Andrew Mechling as a seller. I bought an early MIJ Fender 1957 reissue Strat (JV-00339 - first week of production) and Andrew was outstanding to deal with in ALL regards.
I just bought a 1980 Reborn Old and will forward photos to Tokai Registry soon...
Hello,
To "yellow" your white pickguard dunk it in coffee overnight or until you get the right aged appearance you seek. ONLY replace with a genuine Fender pickguard. Other aftermarket pickguards holes don't line up very well - at least didn't for my '79 Silver Star Strat.
Hope this helps.
