I have a 2005 5.0mpi alpha 1 gen 2 that's all original, meaning nothing's been changed since new. I replaced the manifolds and risers and tune up parts. Now I'm going to start on the bellows and gimbel. I pulled the outdrive (has not ever been pulled) and checked alignment with the old gimbel and the alignment tool only goes in the coupler about 1" and stops. I'm getting deeper grease marks on top of the bar. My first question of probably many is, should I align the engine to the old bearing or just replace it and go from there . Thanks
