When I was filling my tank up with fuel one time, the cap fell onto the pavement and a piece broke off of it. I am still using it but would like to replace it. If anyone has one available, let me know how much you want for it (with shipping included - should only be about 2 bucks using 1st class and a padded manila envelope), and I will gift you the money via paypal (that way no fees are deducted). Remember, it has to fit a 91. I'm not sure exactly what year they changed, but I am THINKING that 91 is the old style - someone please let me know if that isn't correct.
