So I found this vehicle for sale:

https://www.a-gc.com/2000-dodge-vipe...tion-c-441.htm

It was made 11/22/99 at 12:00 PM.

It has a BLACK cap on the master cylinder which I thought was '99 and changed to yellow in the '00 MY. Also, I believe it has Koni's which ran 1/2 year into the '00 model year run.

Growing up an automotive brat, model year change over was normally July and/or August, but I know Vipers were different. When was change over from '99 to '00 and did they use BLACK caps until they ran out? I am probably wrong about something here.
