They are not all the same. The pans for passenger cars and trucks are different and some trucks also had a different design. I'll attach an image of a couple I have. I ended up using the 1956 pan on the 1959 235 because it fit the 1952 truck chassis better. In your case, I think your short term solution should work fine, but as somebody said, you can put a screw in there, too. It might help keep oil from seeping out so you could epoxy better. Just get the pan as clean as you possibly can. I've seen JB Weld fall off oil pans, auto transmission pans, etc that were repaired this way before. Good luck!
