Rear Shackles

Question re rear shaclkes. I was able to wrestle my 7 1/4 out without un doing the rear shackles. No way on god's earth the 8 3/4 is going back in that way! I took the nuts off the rear shackles but the bolts don't want to pound thru the bushings. Not enough roon to get a good swing at it either! Any tricks here?? must drop the springs.
