64-67 B-body 8 3/4 needed

I need an 8 3/4 for my 38 Dodge, it has to be 59 1/2" as I do not want to cut down a longer rear. Looking for years 64-67 B-body only. Here is a copy of an article I'm basing my information on:

There were several different rear-end housing widths used on these models. All measurements are from brake drum to brake drum:

1966-1972 A-bodies - 57 1/8th inches
1962-1963 B-bodies - 58 1/2 inches
1964-1967 B-bodies - 59 1/2 inches
1970-1971 Imperial - 59 3/4 inches
1968-1970 B-bodies - 60 1/8 inches
1970-1974 E-bodies - 61 5/8 inches
1965-1969 C-bodies and 1965-1970 A100 vans 61 3/4 inches
1965-1966 Imperial - 62 inches
1967-1969 Imperial - 62 5/16 inches
1970-1971 C-bodies and 1971-1974 B-bodies - 63 inches
1965-1971 D100 pickups - 64 inches
1969 C-body wagons and 1971-1973 B-body wagons - 64 3/8 inches
1970-1973 C-bodies and 1972-1974 D100 pickups - 64 3/8 inches

Spring-perch measurements between the two leaf-spring mounting pads can range from 43 inches to 47 1/2 inches. This means that the leaf spring perches to mount this differential into your car may have to be moved in or out on the axle tubes with the help of a good machine shop or welder, for correct fitment to your project.
