Superchiefer84, Thank you for the observation. The body screws in most of my Lionel engines are small with a washer-like Philips head screw holding the body in place.
Dean's email to me stated that Lionel had to use larger screws to hold the body on due to the stripped posts.
I hope Lionel has a replacement body shell. Parts don't seem to be available sometimes.
Sincerely, John Rowlen
