Replacement O gauge 3 rail trucks with electrical pickup

Crazy question, what does it have to fit on?  There are tons of 3-rail trucks with roller pickups, the trick is which one do you need!

Crazy question, but anyone know where i can buy one?

This topic did not belong in the 2-rail scale forum since it is clearly asking where to buy an item.  PLEASE make sure that you place topics in the correct category or as close as possible based on the subject matter.

Sorry i am in the wrong forum.  Gunrunner, thanks, as usual.  i knocked an 027 work car off the track and broke the plastic trucks -- i want to replace them with metal ones ... the work car has lights in it -- i didnt know that there were different types of trucks,,,is there a place to go to find out about different types?  thanks
