This is from the 1982 Mack Cruiseliner brochure, although these patterns were used on earlier Cruiseliners. The square grille in the pix can be obtained from AITM under the name Mack Cruiseliner V8 Grille.
While cruising Tim Ahlborn's website, I noticed he took the time to add further to the reference material he already offers those who visit. If you are interested in paint schemes for the Peterbilt 352 cabover, click on the link below, then scroll to the very bottom of the page. There are 5 pages from the Peterbilt paintbook. All for the 352. Tim, thank you for all the reference photos you have provided on your website. They are a real help to those who visit.
A quick note about the "Lexington" scheme for the K100. As far as the big stripes go, it is identical to the "Allegheny" paint scheme by KW. To go with the "Allegheny", you will have to add the small lightning stripes below the windsheild. Look closely at second pic in first post on this thread. You'll see what I mean.
Now these should be helpful. In the '80s, it seems that AMT/ERTL/Matchbox made their instruction sheets in a way that they fit nicely in a 3 ring binder. Each has a nice line drawing of the truck's right side on the cover. So I scanned and cropped these pix. They should be actual size(in comparison to the plastic cab/hood/sleeper) Just print, and draw your stripe patterns.
As far as the stripes shown in the pix, they are the kit stripes for each kit . They could be edited out.
