All but three of the class had 5'-3" drivers: the exceptions had 6'-0" drivers but were later converted back to standard. They were, nominally, rebuilds of the earlier 2F 0-6-0 engines some of which had 4'-10" wheels. Bill Bedford IIRC did a resin body of the 4'-10" wheeled 2F locos, but I don't know if it's still available. Keyser did a cast whitemetal 2F with 5'-3" drivers, I still have it somewhere in the loft unmade.
5'-2" drivers will do the job for you, I think.
