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

No ****? He ordered 5x4.5’s and now wants to charge me $250 to have them redrilled. He’s already built it. What do I do? Return the original axles? I’m kinda upset
Chit if I know. The A body used the 8 3/4 with the small bolt pattern only until 1972. In 1973 they dropped the 8 3/4 for the A body and went with the 8 1/4. How certain are you that what you have is an A body 8 3/4?
