I was attempting to list a set of wheel center caps for my 2007 Ford Mustang. I only got as far as the point where you enter a category number. I cliked on browse and I saw nothing listed as far as anything related to automobile parts. i know these are found in the eBay motors section of eBay. that wasnt listed either. I tried to use the search feature next on the listing page and entered wheels..center caps...car parts...etc and all that came back was category numbers related to toys and radio control cars. I then went to eBay and searched the help section for a list of category numbers. I found the category number for eBay Motors:car and truck parts which was # 6028. I returned to auctiva and entered this as my category number on my listing page. i received a message on the screen in red that this was an invalid category number. Can anyone please help me. I am on the verge of saying the heck with it and going directly through ebay to list them but i dont really want to do that....PLEASE HELP !!!
