Hi, new to forum. I have a question about transfer cases. I would like to put a split transfer in my 75 fj40 with a 4 speed and I assume a 16 spline output. The reason for this swap is that you can buy 4.1 low range gears for the split case. Can the output shaft of the h42 16 spline be swapped for the 19 spline? Can the input of the transfer be changed to 16 spline? Are there any other changes that have to made, drive flanges and such? I know you lose the parking brake on the driveshaft. This seems like a cheaper option than a crawler box, dual transfers and such. I don't want to spend the money on the h55 and have to change the driveline lengths. Thanks in advance, Glen
