rear end swap 8 inch to 9 inch

[cwr68]

I am changing to a 9 inch rearend in my 65 coupe, the unit came from '59 fairlane that had 2 inch springs and used 3 inch u bolts so the shock mount plates from both rear ends won't work. Will the mount plates from the 67 and up work or do I need to go with truck or big body ford car to complete this swap? Thanks for any help.
