I am in the process of buying an 07 hhr and I am wanting to "rearrange" some of the structure. I want to move the b pillar back. I wont have my car until this weekend and I keep trying to think this mod through my head...can someone tell me if the b pillar is spot welded in place or is it stamped as one piece and part of the side of the car.
if its spot welded I could drill out the spot welds and move it and reweld easily.
If it is part of the stamping...that will make it more difficult but not impossible.
I'm down from recent surgery so I cas't just go look and I cant see it anywhere online. I just need some one to peek or take a picture, I'm sure if its welded in it would be easy to tell.
thanks in advance!

It is composed of several layers, some spot welded but is also part of the giant stamping for the front and rear doors.
As Sleeper says it is designed to keep you safe in case of crash - so any major body structure changes will likely compromise the situation,
Moving the B pillar back would also mean major modifications to the front and rear doors, their windows, wiring, internal reinforcement, internal door panels - etc. etc. so if you are planning on doing this
as a backyard project and expect to put it back on the street afterwards, you better just take it to a full-on fabrication shop to ensure it is done safely.
This thread kinda reminds me of the fellow that wanted to turn his HHR into a 4-wheel drive off-road machine.

Thanks Whopper, I'll definitely make it safe! I have a couple of wierd builds under my belt. This one will be frame mounted and roll cage will be added but I'm not going 4x4...I'm going low and chopped.

I once saw this process.
In Russian, this part is called the "bokovina" =sidewall.
In the diagram you see the outer and inner sidewalls. They are connected as two halves of a sandwich by spot welding. And there may still be amplifiers inside (at least on the threshold it definitely is).
You will need 2 sidewalls assembled = 2 sandwiches, right and left. You can find a dead car in a landfill and cut both sides. To Cut the B-pillar approximately as in the figure.
Then the most difficult ... - you have to carefully cut the pillars out of your car and insert the blanks from the dump in their place. This work is laborious and the danger of spoiling the car. A careful measurement is required, a deviation of 1 millimeter is already critical, unacceptable. In addition, you must protect the roof.
If everything is done correctly, you will get something like this.
But you have to do something with the doors, this also needs to be lengthened. It will be necessary to order new elongated door trim, new elongated door glass, new elongated door sill and ceiling trim. And something needs to be done with the rear door openings.
Titanic labor, high costs and the real danger of ruining a good car.
