Based on my knowledge, thus far, on 32 bumpers, yours appears to be an original small knuckle bumper. Finding the right welder/welding rod for the original spring type steel used would be the key for a successful weld, you also would be best to have the chrome removed before doing so, as I am sure you already know!!!Can the bumper in the pictures be repaired?
