What are two used 1977 911 Doors with power worth?

[Argeo]

I am just curious because I am considering getting used non power doors and curious how much I can get back. The doors are in great shape, actually started removing the paint last night. No rust on the outside, don't know about inside. I want to get rid of because I have had it with power stuff. Most of the time they work like old motors (slow but functioning), next thing the fuse is burning out on them. I am tired of trouble shooting electrical gremlins. Just a rough number please.

Thanks.
