Hi I have a club member that has the above locomotive, the front truck came loose and lost the shoulder screw that holds the pilot truck to the frame, he was able to get every part needed from Lionel except that one screw. It is still listed as unavailable looking in THIS part breakdown it is listed as PN # 42
cs-6402539440-p
SHLDR SCR .160" x .335" x 4-40
anyone have an idea for a different replacement screw?
