I had to lengthen my drilled ones by welding, then cutting off and using a lathe to turn the groove for a snap ring and beveled the end a bit. Then I simply wrapped a nail around them to get the ID close to the groove, and cut off the nail to fit. Squeezed with pliers to add a bit of tension. I don’t think it needs to have much spring tension to stay in the groove. Hope that makes sense. So yeah it’s a cosmetic thing
