usually a google image search for 1/32 scale slot car wheels works well for me, then I can see what I'm looking for and get the link directly to a vendor. or you can try this place... Slot Car Parts : Electric Dreams, New and Vintage Slot Cars
it just reminds us daily that "common sense" is not common. and that product packages have to be large enough to have all the required warnings printed on them so the manufacturer can't be sued when their product gets used incorrectly. I mean, why would Apple need to put "do not swallow iPod" on the consumer documentation?
really like the detail work. one minor issue with the detail on the master cylinder... (and only meant to be helpful...) the whole top of the master cylinder is the lid/cover to the brake fluid reservoirs, there would be no single hole in the cover unless someone decided to mangle it for some obscure reason. teh interwebs should be able to supply a decent reference photo.
