I have the opportunity to buy a soft top that was taken off a newer TJ. He is not sure what model year it was removed from. Somewhere between 2000 and 2002. I thought that sailcloth tops were introduced on the 2001 Wranglers. What I need to know is there a sure fire way to tell the difference between a regular top and a sailcloth top? Both of which would have been factory original. I know the sailcloth is a heavier cloth, but since I have never seen one I could be easily fooled.
