As for the front drive shaft spline, yes. There is probably 5 inches exposed. I don't know what it should look like, but that seems to be a lot, to me. I worked on this truck many times before I graduated university, but never got into the engine and trans rebuilding. My FiL had that done at some point after I graduated. Do you have a pic of the other sides of the frame perches? From the picture you have there, they look asymmetric. That could just be an artifact of the camera angle.
