I'm running an NP208 behind an NV4500 currently. Standard 6 bolt GM adapter between the two. I have no idea what the input spline count is currently on the 208. I have to R&R the drivetrain due to an oil leak and am considering swapping the xfer case while I'm at it. What should I look for in the 241/208 regarding input splines for a straight bolt on affair? I can pick up a 205 for about $125 locally. I have not verified pricing on a 241 yet.
