So I’ve decided I want to do a cage chop on my 2020 Pioneer 1000–5. Once I made this decision, I started doing some research to see what people have been doing and what seems to be the most common. I’ve decided that I would like to do 4 inches on the A pillar 4.5 inches on the B pillar and 5 inches in the C pillar.  with that said I think I have everything figured out except for what takes place on the B pillar. I would like to cut out the headrest bar and weld in a bar for harnesses. With that said here is my question and a picture demonstrating what I’m asking. What should I expect behind the added metal That is the gussets for the headrest tube? if I take a grinder and grind the welds, will I have a full tube underneath or is that an area I am going to have to try and repair somehow?
