Just got my first Harley the other day, a 1983 Ironhead Sportster XLX.
I want to replace the fenders and get a fatbob tank. Where is the best place to get these parts and others for the cheapest amount of money? I'm replacing them because I don't like the custom paint job and believe i can sell them. Thanks

 

JP cycles will probably be your best bet for cheap.

J&P cycles *currently has a sale on for the weekend only up to 20% off all orders over $50*, jireh cycles, dennis kirk, ebay

 

Swap meets, E-bay, might even check for bike salvage yards. Also check with your local independent repair shops or find some individuals that are in to choppers or old bikes. These people usually have a few tanks and fenders laying around.
