Hi Alex..... not sure what you are asking......????

The other is the front-most part of the left inner fender......there might be some difference between C8, C15 etc....I am not sure. Apart from that corner I am also interested to know how far the horizontal piece extends toward the rad and engine....(the piece that is bent 90 degrees and welded to the inside of the missing piece and inner fender part)

Not sure if there is a difference between the arches of the C8...C15....C15a.... the inner fender pretty well follows the curve of the arch.

I have taken some measurements and photos from a parts vehicle with no engine ...it is a cab 12 C15a.

In your picture you have colored the front area in rust brown..... that section is spot welded to the side panel. Is it missing on yours??? Can you clarify what specific area you need measuring.....

Here are some photos and can take more if needed.

Cheers
