So my saga continues. I thought I was going to switch lowers but that didn't work. I changed the oil seal, foam ring and dust wiper on my Reba a couple months back and thought I would do the same on my Revelation. I noticed that the revelation does not use the same configuration and just has the foam ring and dust wiper. Any reason for this? When I replace the wipers and foam ring should I add in the oil seal (which usualy comes with the kit) or just put in the foam ring and wiper as it is now.? What's up with that?
