rodneym,
Each time the coupes were in a race they changed there numbers but the reason I put #14 on CSX2602, that was the number of it's debut run. CSX2602 had many numbers associated with it but #26 has been the number if you are building a replica that stuck, maybe because that's the number on the coupe when it sold for $7,250,000. I saw a 1:18 scale CSX2601 marked with a #26 for $360.00 for sale but at that price my buddy will have to buy his own.
