LOL, the same thing happened to me. I had a 66, I ordered a rear bumper from CJPP. Bumper bolts would not work, they were off over 1/4 inch! I thought the car had rear damage, which it did not, (it was a beautiful California car that sat from 1975 until 2014). This is where it get good. I called CJPP and told them about it. They wanted pictures???!!!!?!?!?! Ever try to get pictures of chrome? Anyway, I got my tape measure out and proved with the pictures that it was not properly manufactured. I got the typical like that CJPP uses. "We have not had any other costumer complaints about this." OK well pictures do not lie. So after complaining more, they said OK we will replace it, I said, are you selling a different brand? They said, "No" it will be the same one we sent you. I thought, Hmmmm so what if its the same? I decided to say, "OK please send me another one." They then told me, "Just return it to us and we will ship out another one." I then asked about a "call tag" they said, I was responsible for shipping, I priced shipping and it was about 40 bucks, I called them and told them that and they said, sorry you have to pay for shipping, I said I have to pay for a defective bumper's return? It was a big fat YES. I decided to just order another one......and when I got it, guess what....it was a big fat NO GO, NO FIT. SO I called my credit card and reversed the charges for both bumpers. That was the LAST time I ever dealt with CJPP.
To end this story, I ordered a bumper form a company called "Dorman"
I think, and it fit like a glove and looked great....BUT I still dont recommend any repro, because you just do not know what you will get.
On to my Boss 302's rear bumper, fits like (you know what), I have been looking for an original Ford bumper for years now, the re-poop is still on my restored beautiful car. That sucks!
Sorry for the rant, but it is just unreal.
