Re: determine value of a prop??
Aluminum or stainless? Aluminum would probably be worth around 60-100 if in as good condition as you describe. 100 would be a bit pricey though. Add on shipping and you are getting close to price of a new one. Stainless about 200 --new is over 300. You can advertise it as fitting any three or four cylinder Chrysler or Force 15 spline prop shaft (85-125) from 1980 through 1990.
Getting close to the end of the season here so if you are near the North or Northeast, probably would get your best price if you wait until the start of next season.
