37' Door seal material

[banjoQ]

With all thats going on in the world, I find myself looking for projects to pass the time. I would like to replace the door seal material on my 37' truck cab. Maybe I don't have the correct term to describe it (seal, windlace, ect), but I am having trouble locating anything close. I am looking for the interior door seal that is cloth bound with what might be cord inside and a flap of material for mounting around the door opening. Checked C&G, Drake, Carpenter and no luck. Maybe its not made anymore, but its worth asking here first before I give up. Any help would be greatly appreciated. Take care and be safe
