Did they make 5x4” axles for 8 3/4 rear ends?

I’m swapping out my rear end. I needed axles for the 8 3/4 rear end I found. My car has the small bolt pattern. The rear end builder is telling me they never had small bolt axles for 8 3/4” rear ends. He didn’t believe I had a small bolt pattern so he ordered large pattern. Now he’s telling me they need to redrill my axles? They don’t make small bolt pattern axles? Am I getting screwed here?
I have the original axles that came out of my 69 Dart 8 3/4 small bolt pattern and the rear drums.....they are yours FREE I live in LA CA.
