I am changing my dizzy holder to an aluminum "fancy" one. I have to remove the stud in the case to hold the dizzy (not long enough for the new one) I have it down to take off the current stud using 2 13mm nuts mated together. How do I install the new longer stud? Just thread it into the case using the 2 nuts locked together. Thanks. Tranny fluid changed - thank god for "as seen on Bob TV" apparatus.
