Very interested in this as my 318's gonna need to go soon enough. What's your plan with mating it to your 904? I know you have to hog out one hole on the flex plate but I can't seem to source the correct one.
Magnumdust hit the nail on the head, there isn't a certain hole to hog out, basically what i am going to do is bolt 3 of the the torque converter bolts to the flywheel while it is suspended by my engine hoist. i will mark the 4th that does not line up, also mark the tc and then hog the hole out so i can get the 4th bolt in.
