My two cents, $1,200 for the bow set, assuming it is complete with the windshield bracket, and $800 for the doors, assuming they are complete with the weatherstripping brackets that bolt to the outside edge of them. Quite a bit less if you don't have those parts, as they can't be found, so someone will have to want to mock up something workable (like $500 for the pair without them).
That would be if you sell seperately. If it were me & I wasn't in a hurry, I'd keep them all together & ask $2,500 for the whole set & not really negotiate much. They are worth it to a person with a white original 40 that isn't restoring. The whole set would drop right in & look perfect on day one.
Of note, those are early/soft top door bows, so they won't fit perfectly for anyone with a later truck (bent door uppers) that wants to run their hard doors, so the market isn't quite as large as, "anyone that wants a soft top" so to speak.
