It would seem easier to me to slightly bend the ends of the U-Bolt in to meet the holes in the plate.. I would rather see you do it that way, then try elongating the holes in the shock plate..
Maybe that is the problem that you have now, the U-Bolts are bent out slightly not allowing them to pass through the holes in the plate..
That would be my suggestion.. Bend the bolts to work with the plate..
The only other thing I would mention is this-if you are going from a single leaf spring, to multi leaf springs, you should know that the original shock plate for the single leaf spring had one U-bolt, and 2 T-bolts for each mount.. When you remove those 2 T-Bolts you will have to drill those holes out larger in order for a U-Bolt to pass thru as the U-bolt is larger in diameter than the T-bolts... Is that possibly your problem?
Wait, I just went back and re-read your post, are you saying that when you put the shock mount plate up against the spring perch that the holes do not line up???? If that is the case, yes, you will need to elongate the holes in either the perch, or the shock plate, or a little from both, to get the U-Bolts to pass thru..
