SLEEPYS 69 swinger project

About to start on a 69 Custom. Yours is an inspiration.
I need a driver fender, so I'm also curious about what years can work. You said yours was from a Dart Sport? I thought it would have to be a Dart.

Edit: Partly figured it out: 73 - 76 Darts and Dart sports used the same fender which is like the 67-69 Dart fender apart from marker light/reflector placement. Someone said the wheel opening is slightly different. Not sure on that part. Do you know?
