The other exception is in 1986, when CJ production was coming to a close AMC 20s were in short supply, so they used wide track Dana 44s in some of the '86 models. Bolt on compatible with any '76-'86 CJ, but wider than earlier narrow tack AMC 20s. Use of the Dana 44 in 1986 began somewhere between serial numbers ending with 049379 and 054173. The axles were flanged and 30 spline. Common ratios were 2.73 and 3.31.
All CJ Dana 44s use a 5 on 5.5" wheel bolt pattern.
