Request - door frame dimensions

[wazzabie]

I'm working on replacing the rockers on the 78 k5. I'm not sure if the dimensions of my door frame are correct because the A pillar may have moved. Would some one please share there dimensions so that I can compare? I'm not sure how else I would know if my door frame is true. Thank you.

Being a non-member I can't see that photo. Not entirely sure my drivers door frame is square (broke one of the A-pillar welds) but the passenger one should be. Let me know where to measure from/to.

I don't have a late model but I think this will help.
