Sorry, I've been absent from this topic since I originally posted (stomach virus had my out of commission for a few days).
Anyhow, based on the feedback, I purchased the Lionel FasTrack Earthen Bumper and plan to make a minor modification to get it to depress the reverse switch in far enough. The Earthen bumper was not only more durable, it was also a good bit cheaper. Thanks for all that replied!
