Lionel 18431 Trolley pick-up or slide plate or collector assembly part number needed

Send me a picture of the roller pick up assembly. Maybe one of the old original pick up assembly would work. Do you have any idea when it was made??

Lionel had a series of 42 + supplements with all the diagrams and parts numbers which I have.    I could look thru those for you.    Thanks

Thanks both.  The trolley was made in about 1996.  There is no roller, just the slide which appears to be the part Grampstrains indicated.  I'll order one to try and get this trolley back to working properly.  I have to say, I prefer the postwar #60 trolley, although that is quite a bit noisier.
