Price for PA28-180

What do you think a reasonable price for the following would be.

PA28-180B (1963)
3700 tt
1880 smoh (runs fine with compression in mid or high 70's I believe)
800 stoh
mk-12D
ADF
Average Interior (maybe 5 or 6) serviceable but nothing great
Paint flaking off in many places. Will need to be repainted.
there are a few skins (left and right flaps and left stabilator/elevator)
that have either dents or small patches, and would therefore need to be
reskinned before painting.

Can you give me a rough ball park of what this would be worth? I know a lot
of Cherokee 180's sell in the $35-$40k range, but with both high time and a
need of a repaint and some other exterior cosmetic work, I don't know what
that does for the value.

Thanks

Billy
