8 3/4 fit help please!


Just finished a 70's A body, 8 3/4 with new BBP axles, poly bushing etc, and about to bolt into my 64 Dart Convertible, but it doesn't appear to be lining up to the stock holes in the frame! Did I puts the cart before the horse?? Do I need to move the spring perches!
Or should it bolt right up? I can loosen everything to give me a little wiggle room!

Thanks FABO
