Driver's side rear panel help
 

Hey Guys,

I have discovered a rush issue on the rear panel at the bottom. The one where the rear quarter window is housed. I have been having some water issues but the multiple water tests I have paid for said there is none. Explain this rust then, "experts".

I think need to replace it with a new panel. Any insights on how to do that and where to source a panel from? I think I will reseal the window too when I do this to make sure the there are no water issues.

Any advice would be helpful.

Thanks.

No one has ever replaced a panel before?
