Hello, I just bought a factory new transfer case for my truck and mistakenly thought that all the 98+ electric shift transfer cases were the same, but I've noticed that the cup for the front driveshaft is slightly different, and it supposedly doesn't have shift on the fly 4x4, which I can live without. Will this new case bolt to my M50D-R1 and my front drive shaft and play nice with the 4x4 computer or should I just return it?. Thanks in advance.

 

The transfer case will for sure bolt to the trans

And the front drive line hook up looks the same on both, CV joint, remove the bolts on CV joint and pull off drive line, you will see they are the same
