truck box latch

This is to replace the latch piece on a truck bed toolbox. My uncle called and asked if I could make him a set for his toolbox. he sent me his broken set to take measurements from. I didn't put a hole in the fin because on my toolbox the spring clipped to the outside of the fin. When I sent the printed ones to my uncle he had to drill a hole in them for his spring to sit right. so far they seem to be working fine. used PLA will try ABS if they do not hold up for very long
