[Second Series]

I didn’t understand that document either. That first part is for a plate that screws to each edge of the firewall on the right and left side. The plate fills a hole that the inner fender does not cover. Picture of that area. I’ve seen clutch head screws, or hex head used to secure the plates. My plates were lost at the custom shop. I found some at a junk yard in Montana. Picture attached, you can see the staples that held the seals. My truck has the floor brake lever. If your truck has the foot operated parking brake, the driver side plate will be L-shaped.
The second part of the document is for the front of the inner fender. Picture of the inner fender on it’s side, and picture assembled.
