Alright, here's what i have in numbers from Moog for a 2 1/2" wide wedge;
K8878 1/2 degree
K8882 1 degree
K8886 1 1/2 degrees
k8890 2 degrees
K8894 2 1/2 degrees
K8898 3 degrees
K8902 3 1/2 degree
K8906 4 degrees
I did come across an Amazon listing for AC Delco wedges, but they did not come up as fitting older trucks. I'm going to check for a different source to verify weather Amazon is correct on that. The AC Delco shims were listed at being 2 inches wide, and seem to be available in 1/4 degree increments.
