Hi David and welcome to the site,
Just picked up on your post - technically speaking I am in a different country but not that far away from you as I am just across the Border in North Wales
I presume the Porsche you have is based on the Kyosho Pureten Alpha GP3 - If it is, let me know and I will e-mail an exploded diagram of the car with all the part numbers listed. You will need the numbers for identifying the parts for when you order new ones.
I am not sure how many model shops are left in your area but I can certainly point you to a good couple of websites who do stock all the spares and provide a good service.
Let me know and I'll send you the info.
Regards.......Mark.
