The little somewhat of a seal in the end of the driveline should be renewed while it's out, and I did the flywheel bolts new and replaced the header to center section gaskets and bolts and nuts. And before you start you need to get a tool bent -built or borrowed for one of the trans to motor bolts. I took a cheap wrench and heated it and put a little less than ninety degrees in it sideways to get it out, maybe an s-shape wrench or stubby wrench would do it if you have no torch. But you should get that wrench before you start, I had to dog off in the middle to get that solved. Good Luck and Godspeed Sean
