Hy again Matthewnotmatt, Okay, by size only Chicago Rawhide part number 31269, or National part number 455145. Once you find a supplier of either of those part numbers, take your old seal with you for comparison purposes. The other identification I was looking for was the letter designation of the model of your truck, AC, AF, ACS, ACW, CCW, CFW etcetera. My old Victor seal catalogue is the most complete book I have, but unfortunately I need the letter designation to zero in on the correct part number. I did try to confirm which Victor part number was the correct one by using my seal interchange catalogue, unfortunately none of the possible Victor part numbers appeared in my interchange catalogue. I hope the numbers I did find are helpful.
