Need help with driver's door adjustment on 67-72 Chevy Truck/Blazer

[kna4977]

I recently purchased a 72 K/5 Blazer that has about a 3-yr old resto. Please see my aviatar. It is rust free, and looks great except the driver's door doesn't exactly fit at the bottom where it meets the front of the rear quarter panel and rocker. It sticks out about 1/4". What's the best way to get rid of this and make it fit? I have tried adjusting it myself, but it doesn't latch well when I do. Maybe I'm not adjusting it correctly. Any suggestions would be greatly appreciated.

thanks,

Matt
