With this topic back in play, I wish to add an update to my original post. Fortunately, I was able to obtain replacements for the damaged underbody detail casting on my Lionel passenger cars from Lionel. At $10 apiece it did not break the bank and I did buy extras. It is becoming increasing difficult to obtain replacement parts for modern generation trains and I was lucky to find these parts still available.
Now if Mike Wolf would just re-introduce the P5a Boxcab and run off some spare body shells.......
