OK, thanks Greg. Don't know how I could have missed that, but yes sure enough it's right there. I'm going out wheeling with a large group of Toyotas this weekend, so I'm sure I'd be able to get some measurements of the different T-case styles and see if anything would be a bolt-on replacement for my '80's cases.

In the past they used to not recommend the 3.0L chain drive cases for a dual setup, but that opinion changed and they now make the adapter for this. Does anyone have some opinions on the chain drive case vs. gear drive in terms of strengh and reliability. Only reasons I'm considering the change is because of the slightly lower ratio (2.57) and them being newer an quiter, but the mods required to make the changes may not be worthwile esp. if I suffer strength issues.
