When I rebuilt my 65 C10, I read somewhere that you could use the door seals from a later model Honda Accord (I believe it was). Do some digging and verify what model Honda it is because they fit perfectly and worked better than anything you will find that is specifically designed for the truck. they are press on as well and you don't have to jack with any glue.
Again just do a little research and find out what the specific model is and then you can buy the set online. If you cannot pinpoint which one it is, give me a ring at 417 389 9561 and I will see if I can dig through my receipts for the model I used.
After I posted this, I went out and did a quick search and found this link for you: http://67-72chevytrucks.com/vboard/s...d.php?t=741910
It was a 2006-2011 2 dr Honda Civic but please verify before you purchase. You will be very pleased with the fitment.
