I've always used a hammer and punch for this job.
I used grade 8 bolts when I put my Duster back together. I also placed a 1/2" spacer block in front of the leaf hanger to center the rear wheel in the wheel well.

I just bought a Dart Sport, I couldn't figure out why there was a stack of washers behind the front leaf spring mount. Now I know why.
I why make a proper spacer when I install me new rear leafs.
Thanks
