52" vs 56" spring, short and long bed conversion. HELP!!

[cochino12]

I pulled the bed off my 3/4 CC that I will be shortening last night and now I have a few questions.

I assume the axle will be centered correctly when swapped from 56 to 52", right?

I've done some reading and it sounds like the frames should already have hanger holes for the shorter leaf springs. Am I missing something because I dont see the holes? Is the extra length is in the rear of the leaf pack?

I dont remember swapping leaf packs when I shortened my old c30? Can I run the 56" leaf springs under my short bed, it doesnt look like it?

thanks in advance for any help
