does anyone have any experience with this case. I have a 99 yukon and am planning a SAS for the front, but want to ditch the 246. I could just do the easy 243 swap (don't really want to cut holes in the floor of the truck for a 241) but why not do a 263 swap. Thicker chain, I think the gearing is the same, any reasons not to look for a 263 1st.

thanks
