### ⭐⭐⭐⭐⭐ 







  
  
    Good Value for Money
  

*by W***N on Reviewed in the United States on September 18, 2020*

Bought lid and bottom to replace 20 year old bottom and top. Probably could have used my old top but to ensure not having a difficult time making it fit on new bottom ordered this lid. Fit perfectly and gauge reinstalled with no issues.
