i was just wondering if anyone had minumum of 2 griffen center caps (for a '91 900 turbo convertible). The part numbers on the back of the caps are 89040, 4199360 and 105122352. Not sure what these numbers represent but the caps are honeycombed designed with the middle of the cap elevated with 12 sides saying saab in the middle (terrible description but the best i can do). Can anyone please help me! please!!!
