4 sp to th400

[hogwild91]

i want to put a th400 in my 91 blazer it has a 4sp manual in it right now they tell me it will bolt up to motor but what about my transfer case its the stock one that came from the factory i dont know the number, what about drivelines. i plan on just putting in a floor shifter. what do you think

Transfer case should be the same, the NP241 that came in the 91's w/ the SM465 had a 32 spline input. I don't know if the adapters are the same(but I'm sure someone will post up).
