Thanks Terry,
Regarding spares, I am fairly lucky as the my car is complete and runs, but currently has foam tyres fitted which are badly dried up. (hence the need for some new wheels)
I was hoping to race it in a retro class, but may just keep hold of it as its a bit too rare. (shame as I've wanted one since reading the review in Radio Race Car in the 90's!!)
If anyone does find any spares or a donor, I would be interested in it!
