rear quarters lower 2 inch of b pillar and heater channel from b pillar back to fender. So basically on the exterior I have cut a 4 1/2 inch section up from the bottom and straighrt across from b pillar corner to the fender bead line. So needless to say the heater channel is shot on the outside inner is fine. Merideth hooked me up with rear quarter sections. So do I cut panels and patch or cut and weld the entire section channel and all. I guess I am asking what is a stronger fix, just dont want to do all this for nothing.
