Parts Source Needed for Tokina Lens

Hi All, This is my first post as I just discovered this forum. (I’ve enjoyed reading many posts here and likely will spend more time here than I should…) I am in search of a parts source for a Tokina AT-X PRO 28-80. I got a drop of salt water on the internal contact ‘finger’ that wipes a circuit board to tell the camera what focal length is being used. I was successful in cleaning the mess (Late the same day that it got splashed.), and verified it worked, but then accidentally wiped it with a Q-Tip and bent the contacts. ;-( The good news is that the parts are replaceable (photo attached) and it does not appear that there is any other damage.. Does anyone know how to go about getting Tokina parts, or if there is an exploded parts diagram? (So I can at least reference a part number.)

I'd just go to Tokina. They're right near me here in Huntington Beach, CA. I've had them do work on my lens & they were quick and did a good job.
