Thank you for thinking of us :-)
I don't believe I could find the little things like these from other manufacturers.
I've had my diff for quite some time and recently got back into the hobby full force. During a tuning session I made an adjustment to my diff. Well it's been so long I forgot this piece is delrin and not alloy. I managed to break it :-\(it didn't fail on its own). Well sure enough Phil is thinking of us and offering these separate for replacement at a great price. I purchased two just in case ;). As usual a quality product.
