The best rag joints are NOS - nothing compares to the originals. Napa has a good one and you can buy the refurbish kit to save about $10. There is one that Gary1999 uses. I can’t think of the name but can picture the box, it’s green. Come to think about it I bought some from Gary about 10 years ago and still have 1 or 2. Let me know if you want one.
