What year is my cart (see pics)

[fredsmom6]

I acquired this Western Golf Cart which my Dad had. He bought it used and had it a few years. From him, it went to my Niece in 2016 (hence the now Kubata Orange color and the frilly roof fringe is gone). Now it has come to me. No one seems to remember the cart year. From what I have read, the first three digits of serial number reflects a 300 model. Then the next 2 digits normally represent the month and year of issue. My #4 digit is a "1" and #5 digit is a "9", which I decifer out to Jan of a year that ends in "9"

Can anyone with knowlege of body types help out to pinpoint the year of my cart? All help is appreciated!
