Bumper pins?

[Dennis and Melissa]

I’m not even sure that’s what they are called.  But mine have started to fail, even wiggling out on occasion. 😩So I want to buy 2 new ones. I can’t find them on the internet and the mothership doesn’t have them for sale. 
 

Any ideas?

An occasional good cleaning and a shot of WD-40 will make these things last a long time.  Pay particular attention to the little "ball" in one end and the "push button" in the other and also give the holes in the bumper a little shot of lube (WD-40 or something similar) from time to time.

p.s.  you might also take a look in Tractor Supply if that is easier - they used to carry these pins.
