I am looking for 2 pair (total 4 trucks) of truck from a Lionel 6-38056 M1a or similar. Lionel item number is 6938056T50. Lionel has them but wondering of anyone has some to spare. Will consider similar looking 6 wheel trucks. I am sure Lionel used them on other items. Picture is from the Lionel website. Also need drawbars and couplers,
