I have a underground service ran in PVC pipe, I have to swap out panel "service change" existing is a old zinsco ,Knock out for service is right in the middle of existing panel, I'm putting in a side by side new main, I need to move my PVC service conduit a few inches to the left, parts house does not have the PVC offsets, only the aluminum ones, if I use the aluminum offset do I have to bond it to panel thank you
