hi joe,ecklers sell the ralley sport silver in a spray can & can deliver this to you,or powder coating would look really trick but not original.i just use the spray can method ,just about every time the centre cap comes off the paint chips and i am forever touching up the rims.from factory allso i heard that it is comon to find runs in the piant on the rims,apart from checking most of my books i came up empty on the colour code,maybe murry could help out on this one?corvette america have listed part 1593 rallye wheel authentic silver grey piant in a 11.7 oz aerosol can for $11 ............hope this helps let us know how you go.:23
