Straighten the bumper mounts or get new ones?
Straighten them. They are pretty squished, but can be straightened (don't use heat if you can help it.) It'll probably take a shop press to accomplish it.
Original bumper mounts are spring steel and have nice rounded corners. The aftermarket replacements are mild steel and have sharp corners. Overseas junk.
Maybe you can find some decent originals by posting a want ad here or finding a wrecking yard with old stuff.
Your engine seems to be a 1945 216, cast Jan 6 1945. The 3838549 number goes from 43-53. Not that it matters.
