The attached scan is from an ihc publication..."accessories for International trucks parts marketing" with a printing date of June, 1979.
I'm not certain who the vendor to ihc for those items was back in the day, but I'm sure it's similar to the kayline mount you have. Many of the items such as bumpers, etc. Were supplied by fey.
Jeff May know the oem sources for some of this stuff. This sheet is the best I can do for ya!
Edit! Here's another attempt at a scan, this one works! Thanks Robert!
Edit II: well seems something is corrupting the file when it's uploaded to the forum, when I email it to myself it opens as normal, when I download from the forum and open, the file is then scruud. We'll look into this.
Edit iii: here's the file as a jpeg, try this.
