spring hanger bolt hole alignment

[82Cecil]

This project is getting humorous. After all the fight to get frame rivets out, and the original hangers off, I now find that the 2 1/2" Mc Gaughy rear leaf spring hangers don't line up with the holes in the frame.

They are off about 1/8th of an inch on the bottom holes and about a quarter of an inch on the top ( wide side ).

Is this the norm to have to drill ( offset ) your own holes to fit the new hanger?

Thanks again for helping, the people on this site are awesome!
