yea instead of having a tailshaft housing like yours the 4wd has a adapter housing that the transfercase bolts up too

I like the way you did yours as well. It just shows there is more than one way to do things!

For you guys that added a mounting tab to the back of your crossmember, How much clearance to the pan do you have? Can you pull the pan without removing the crossmember? It's not much extra work to support the t-case & remove the crossmember, but I just want to know. Pics of the pan/crossmember would be cool if anyone has them.

Thanks in advance!
