Tronman - Thanks for clearing that up. I've got a partial '60-'66 FAM (someone gave me an electronic copy of what was thought to be the full FAM but sadly it's only a partial with lots of duplicate pages and not in any sensible order), and it took me a while to scan through that to see if I could find anything related to your specified area of the bus. The only diagram from my "FAM" related to your question is the diagram for the forward front of cab floor mount in pic 1. It indicates the "No. 1" mount in lower left applies to the S60 SBC (School Bus Chassis) model. Other than that, none of the front fenders or related bits and pieces are covered in my "FAM".
I have a 1966 Chevrolet Specialty Parts Catalog that shows an overview of the '64-'66 60 Series truck which I've attached for reference as pic 2. From that point, I did some web wandering and came across the picture of a 1965 S60 SBC (pic 3) in this
1965 Chevy Bus Chassis advertisement. I also snagged some still pictures (4 - 6) from a
YouTube video to possibly provide some perspective/reference.
A little further digging led me to this
page of a 1966 Chevy Medium/Heavy Duty Master Parts Book. Parts Group 8.130 is for the Front fender and related parts located on nearby pages. Unfortunately this reference only lists part info, no diagrams or pictures.
A couple of observations from all this info. The Master Parts Book lists a couple of different front fenders for the 60 Series trucks, depending on the front axle equipment so hunting for other fenders or related parts may need some reference materials handy when comparing to be sure you've found what you need. My second thought is from the pictures and diagrams I've found, most 60 Series front clips and related parts should work for your Bus as they appear to be basically the same whether from a regular C60 or S60 Bus.
Unfortunately none of the 60 Series fenders and related parts are being repopped, so you'll likely need to find a donor vehicle or fabricate rust repair materials to fix whatever you have that needs replacement.
Sory for being so long winded. Just trying to offer what I can to respond to your need.
