Restoring my Super sprint
 

Hello friends, Greetings from Catalunya!
My name is Jordi and I'm restoring my old Nikko Super Sprint, I hope you can help me find parts. I'm new to the forum and I do not really know if this is the right place to put this question ...
I am interested in all kinds of parts, or know if there is possibility of alternative parts for other car models.
I would be very grateful for any help!

Thank you very much to all and apologies for my English.
