Welcome to the site. I don't recall having any of those cards, but by going to the specific card pages, you can see a list of who has that card in their collection or for sale/trade list. If anyone has them, you can message them to see if they would be interested in selling/trading. Best of luck on finding them. If you have any questions about the site, feel free to reach out.
Matt Kenseth card collection is nearing 50% with over 2300 different cards. Always looking for the missing remainders to get to 100% completion.
