Does that inclued the adapter for the 4l80e 2wd to a 241???
31 spline in a 241 is achievable by swapping in an input gear from a NP271. A needle bearing "adapter" needs to be machined to accept the smaller 241 needle bearing in the 271/273 gear. We do this regularly for our hardcore Diablo crawler boxes. It's likely not cost effective to perform the swap on the 241 unless you can do the machine work locally.What options would i have with a Ford t18 and np205 all 31 spline?
