Newbie wondering what year/style of bucket seats are these

Thanks to all that have replied and given ideas to help my son out ! I hope this covid crap gets wrapped up enough that Mopar fest can open up and we can meet up with some of you guys this summer. Steve- did you get your welder fixed or did you move on to a better one? Ours is still going strong( fingers crossed) , Conner just finished putting in patch panels in the front floor pans of his dart. Now on to his seat backs... Thanks again guys.
