TrainLarry, again thanks. Do you have another source. Your first "here" takes me to a supplier I have had problems with in the past --2 or 3 times. Maybe The Train Tender you referred me to earlier has these parts?
The second "here" does not picture the small plastic insulator directly under the "rail glide" itself.
Again, I apologize for not using the correct terms. I have even looked for a diagram from Lionel that spells out the major parts of a F-3 --I don't need a diagram of every spring, screw, washer --just the major parts taken collectively.
