It should be noted that in 1969 the assembly line used level gauge/indicator #3905449.Used on all vehicles w/Turbo-Hydra from 1968-73 and later superceded by #1387568 around 1976.Then superceded again by #1239014.
In 1969,the assembly line tube housing was originally #3974420 used from 1968-73 on same.It was later superceded by #330120 around 1976.
Although not considered concours correct,there is nothing wrong with using these later issued superceded parts together.But be aware that pairing one with another,before or after the other was released,will result in a false level reading.
