I have 10 Traxtech 45 degree T-mounts for their tacks. Most Lunds use a 45 degree mount in their SportTrak, but some are a different degree. Anyway, these sell for $40 USD a pair. I will sell mine for half price and this includes shipping in the continental US (Canada will be slightly more). Paypal only please. Please note that one of them had the small threaded locking T on the mount break. I used a die and recut new threads and it appears that it will work but you may wish to replace this small piece. You can buy these directly from Traxtech as a replacement part but you have to contact them direct as it is not listed on their website in the list of standard replacement parts. $100 for all ten.
