8-3/4 rear removal with springs

So I'm trying to remove the 8-3/4 rear and springs from my 70 Dart as a unit
Removed bolts from rear hanger no problem hangers dropped
Front hanger removed nuts, ok, now the 1/2 bolt for the spring eye extends into the frame and is preventing the whole assembly from sliding out
It looks like I now have to loosen or remove the u bolts holding the rear to the springs.
Any advice ? Am I on the right track ?
Man I'm getting too old to be doing this crap
I have some advice>> Never like NEVER save a resto for when you retire LOL
Thanks
