If you are looking for a chrome dipstick tube - just pick up a golf club at a garage sale or 2nd hand sports store (cheap undr a $1). look for an old club with a stepped chrome shaft. useing a tubing cutter match up the lenght and diam. of your dipstick tube to the correct section on the stepped shaft of the club. be sure to debur the inside of shaft after cutting. Works great and looks good and costs next to nothing.
