Idler Arm hitting header.

AW shucks,you can just call me AJ.
So you're saying the PO also had fitment issues in a 76 Duster? And he told you this before you shelled out the green? And you still bought them? Ahem....Give your head a shake! I hope you got them cheap.
In that case, you can bet the PO tried everything already. If it was me,I would dig out the tools and start cutting.
