Hey I'm building a truck right now. running 12v and nv4500 in a ford. my question is I have a 241 DLD hanging behind the trans now. I have a ford NP271 that I have sitting in the shop. I did some research on here and I cant find exactly what has to be done to mate the 271 to the nv4500. It looks to me that guys have done it. comparing them the splines are different and shaft size and lengths are different. Looking for some help from some one who has done this.
