I love these knobs. I have used them on all my CJs. This is a great alternative to the cheap "OEM" plastics I've used in the past. They're a bit pricey but I think they're worth it and will last a long time. You can tighten them very tight and secure them with a set screw. I used a small lock to make sure they didn't come loose. They can also be drilled if the hole is too small.
