I agree that the cir-clips are tough. I had come across the need a couple times in the shops I ran though. I have had the same pair of cir-clips in my box for years though. I know of that slide hammer set up but no longer have that specific tool and attachment. When in the shops, before retirement, I had a complete set of Snap On tools mixed with Mac and Matco and Cornwell and Thorsen and SK. My retirement and move caused me to sell off some specialty tools and that set was one of them and have not re-purchased lots of those specialty tools. I believe I can rent though. Thanks.
