My '93 American Standard J was that colour - I think they called it 'lipstick red'. I have attempted a similar search but years ago. Fender did continue making 22 fret necks into the '90s but of a different design, incorporating a ramp at the heal. The reason George Binda re-designed the bodies which resulted in a longer top horn was to make a full length 22fret neck work. Finding a late '80s-early '90s American Standard neck is going to be difficult. Unless someone is 'parting out' their bass (unlikely) you'll be hard pressed to find one. A re-fret on your neck would be your only option.
Hi JIO, thank you for kindly replying and for the valuable additional information regarding the neck. I imagined that it would be a difficult neck to find. Your Jazz was and still is a beauty! I had what I recall being a tobacco burst longhorn Jazz bass which I bought new in 1992 just a few days before my father sadly passed away, so that year has much significance in my heart. I remember there were a fleet of them at our local music store at the time, and the one I bought simple "had it" so I didn't hesitate to buy it. I kept it for many years, but then gave it up when I was done gigging... Little did I know that I would return to the stage years later with the same bandmates!
