Hope I don't get in trouble for this but just trying to help folks who help me. NPD looks like they are getting out of the 72-93 sheetmetal business. I just paid $31 apiece for two fenders. They are 20 gauge just like my old ones. Don't know about fit yet. Shipping was $150. They have other parts too.
