Passenger Door is stuck shut.

Guys and Girls

did search and tried the remedies in the threads I found

I picked up a 64 c10 at the start of this month and I have been collecting parts for it. I want to start breaking down the front end for the 72 crossmember I have but I cannot get the door to open. I have pulled the door panel and spray WD-40 and pb blaster on the latch inside the door . I've tried prying up on the door ,pulling hard and I can't get it open.

Do you guys have anything other ideas?

Thanks in advance!
Chris
