adjustable panhard bar issue!!!???

[kiles2001]

so I lowered my 69 long bed 3" and installed 295/50/15 on the rear end as a result my passenger side tire rubbed against the inner wheel well of the bed, I bought a panhard bar from early classics, I adjusted it all the way closed and now the passenger side has about 7/8" clearance and the driver side has about 1/4" clearance in order to fix it I would have to close it even more but it has now been closed all the way!!!! UUUGGGHHHHH!!!!!! I would be able to fix the issue if I took out the nut that is in between the adjustment hole and the bar it is about 5/16" thick, my question is... is there any other way to resolve the issue? can I just remove the nut? it wont turn loose since it only has the adjustment on one side? do I call early classics? I beat it into place and doubt they would be ok with it... please someone help...!
