Suicide Door - bracing

[biohazardbill]

For those of you who have done suicide doors, how did you brace the rear cab pillars? I am going with a 2 hinge setup. I am trying to preserve as much space behind the seat as possble. I thought about cutting a 1/8 inch piece basically the full pillar on the backside and "spot weld' in several places then have another piece like 1/16" inside the door jamb. This would i believe create a good sturdy mounting surface. The bottom of the pillar would be supported by the crossemeber that also supports the floor pan. The top is where i am more concerned. The way the pillar is attached to the inner panel as well as the others, think that would be enough support?

Sorry for all the different questions lately but when im at a stopping point on one section I am trying to move to another area. Id like to get the truck done sometime before I retire lol....
