Figured it out, it can't be done at all as the system will only allow 1,000 trims per listing and even though trim has absolutely nothing with this item we are forced to select it in order to save the information. And selecting "All Trim" also changed every year range I had just spent the time researching and entering in to, yep, all years. Wasted an hour and a half to finally discover that once again the one size fits all general policy prevents me entirely from listing this item correctly. Our item fits too many vehicle applications which one might ordinarily think would be a good selling point. Not here.
