question about VIN and body styles

Using the info on this page: http://www.lhmopars.com/vin66-74.htm#1973
And here's my VIN: VL29G3B

For body style, you have 2 door hardtop and a 2 door sports hardtop. What's the difference? Mine is listed as the sports hardtop, would that have a vinyl top? Mine has a vinyl top but I never knew if it was original or not.
