i need to have a splined coupler made that has two different splines. i need to put together the output shaft of a th400 and the input of a sm465. so it is probably 32 spine to 10. not sure i'm just in the early stages of the process. i'm just trying to make sure i can find a manufacture that will make this for me. this will only have to be about 10" long and have two female splines on it. have any ideas of the cost?
