Cut bar stanchions? Looks like #6 on the 6-11126 tender parts breakdown : https://www.lionelsupport.com/...53-955d-5f337f8b0371
Lionel uses flat rate shipping so I'd find some other parts to buy, smoke wicking, fans, etc so you don't pay $10 or $12 for those two little stanchions.
Maybe another forum member will chime in with another source.
