Wilde Racing Products...all kinds of slot car products. Check this site for a list of products, which is Eagle Distributors, but you must be a business to order from them. I purchase mine from my local slot car raceway (Marks Model World), or you can find another company to buy from, also ebay sellers have some available, I just hate paying shipping if I don't have to. https://www.eagledist.com/ Click on 'search all vendors', then drop down to Wilde Racing Prod., and hit search bar.
Thanks guys. I dropped it off yesterday to the guy I was building it for, which in turn is for his brother who is 77 years of age. They all seemed quite happy with the representation compared to the original 1:1.
