Best Inner Fender Repair Panel?

For a 70 GS - I see CARS (http://www.oldbuickparts.com/product_info.php?products_id=9222) and Year One (https://www.yearone.com/Catalog/196...repair-panels_inner-fenders-and-repair-panels) sell repair panels for the passenger side inner fender. Does anyone else sell them? And are these the same or is one better than the other?
Thanks!

 

Same vendor sells them to multiple places

 

Thanks Mike! How's life in Topeka these days?

 

just trying to keep moving
