Thanks for all the comments.
Lionel originally shipped the wrong part but after several days, reviewed the pictures and the correct part was received 12/23/19. Installed today without a lot of (some) problems.
On the way to the garage to put on track, my wife looked at me and said "good luck" with a smile, my mechanical skills have a lot to be desired but I did good this time.
Thanks again
MERRY CHRISTMAS
Brent
