its beause it is uncommon, not because of the size. A front fender for my 82 185s is nearly 75% cheaper than the one for my 86 200X. There both about the same size, but there are alot more 82 185's then 86 200X's so, they charge more for the fenderrs because of the lesser demand and that makes the cost of making them higher.

There are 3 kinds of people in this world, Those who make things happen, those who watch things happen and those who wonder what the hell happend.
