I have a 1979 Dodge Colt Wagon. Looking to sell but also looking to find out how much its actually worth. Anybody?

I have a 1979 Dodge Colt Wagon. I swear everything but the waterpump is
original. 2.3L engine, 4cyl, 5 speed, with the push reverse.A clean title, Im
the second owner. Body is in almost perfect condition. The paint is fine,
original as well, it just has a dent on the hatch door. its big enough to pop
out. With that reverse where you have to push down on the stick then
right and down, at the bottom of the stick theres a boot, and inside that
boot is the mechanism for the reverse and a cup with two ovals to fit rods
in at the bottom. Well part of that cup blew out. so i just need the stick and
the whole thing runs.. or well drives again. Im also trying to find out how
much its worth. I know alot about the car already and how rare it is.
Theres only two in my state and I have one of em. Help would be much
appreciated. Thank you
