Thanks for the assistance folks, Mustang now back on track.
   

Fitted an uprated 21k Pioneer motor; front tyres are Scalextric 70's Camaro W9808 as suggested by Tel; rears are WaspSlot #18 SCX NASCAR urethanes. Just need to take the tread off the fronts to lower it a bit, coat with nail varnish and it is good to go. Worth noting that tyres are completely interchangeable between those three types of car.
