I need to buy panels for the left and right side below each door handle... is this called the rocker panel? I usually buy from Z Car depot but i dont see anything there. I might be calling it the 

wrong thing?

thanks

 

 

Yep, looks like it from your picture.  Check out KlassicFab Vintage JDM, I've been hearing very good things about their parts.  If you do not see what you want on their website just contact them since their website is not current with all their parts (they are constantly rolling out new items).

What you are pointing to is the inside rocker panel, this is what you are looking for, they come in left or right.

i actually meant the part that covers this. Is there some kinda leather vinyl piece that snaps into it?\

There are multiple pieces that cover all that.

There should be a long curved sheet metal piece that is vinyl covered to cover the inner rocker. It attaches with some small sheet metal screws. The piece has a smaller curved section on the top that secures the door weatherstrip along the pinch weld.

Here are a couple of pics from when I was taking mine out.

Here is before removal.

thanks... big help there. I think i found what i needed at zstore.com (if they are in stock)
