pre war 259 help

I have a prewar 259 loco i need the roller pickups and tabs that hold them on. The rollers that are on there now have been solderd on. If anyone knows where i could buy a replacement set it would be great

Two excellent sources for prewar Lionel parts are:

Olsen’s Toy Train Parts (http://pictures.olsenstoy.com/search_lionel.htm)

George Tebolt Train Parts (http://www.georgetebolt.com/)

Thanks i will give them a try
