Presidential Dollars (Coins)

I am trying to finish off my presidential dollar collection. As you may expect the coins after Garfield (2oth) are difficult to come by.
I have the following which I would gladly trade for the counterpart.

Harry S. Truman P would trade for D
Dwight D. Eisenhower D would trade for P
John F. Kennedy P would trade for D
Lyndon B. Johnson P would trade for D
Richard Nixon P would trade for D
Gerald Ford D would trade for P
Ronald Reagan D would trade for P

also need;

Millard Fillmore D would trade for P
James Buchanan D would trade for P

I basically need all the presidents from Chester A. Arthur to Franklin D. Roosevelt (P & D). If you have any please let me know what it would take for you to let them go.
