New Leaf spring shackle question

[Gos1]

Hi everyone,
Been a while since I have been on here. I hope everyone is doing well. This past weekend i replaced one leaf spring shackle (drivers side) on my car. It was bent up pretty bad from the car getting hit from behind years before i bought it. Anyway i got the old shackle out (with help from my sawzall) and replaced with a new one. Everything fit in fine, but when i lowered the axle to the leaf spring, the guide pin and the perch do not line up. My question is: is the shackle supposed to be left loose until i line everything up and seat the axle correctly? Is it supposed to just line right up with the shackle tightened down? Or am i supposed to "muscle" the axle into place (the passenger side is still all together, i did not remove anything on that side, just the driver side)? It is not off by much just about the width of the pin itself. Should i jack up the other side too and remove all that hardware, line up the axle and then bolt everything back together? Not sure where to go from here.

By biggest fear is that the frame is bent and I am hosed.

Anyway, any suggestions, thoughts or ideas will be appreciated.


Thanks
Gos
