Seriously? You just advised him to commit the offence of driving with plates not authorized for his vehicle. That's a no set fine offence and it's arrestable.
The HTA has no provision for allowing you to attach "unattached" plates to a new vehicle. The only thing you can do is attach the plates from an old vehicle, of a similar type (that you no longer own), to a new vehicle for 6 days following the purchase.
You should be careful about giving incorrect advice on this forum.
NOTHING I SAY ON HERE IS LEGAL ADVICE.
