Make sure after you take the shift lever out of the transmission(not the Tcase) take a paper towel and gently shove it into the hole to the transmission to block it off, then just go ahead and take the other 4 bolts off to remove the tower(I think they are 12mm bolts) do this before you try to take the shifter bolt out(the one that is replaced by the new one in the kit) this way you wont have to worry about dropping the broken bolt end into the tranny, I did this because IMO its always better to work alittle more to be safe, then have to waste the rest of an evening fixing something that shouldn't ever have been an issue. Besides, it was simple to take the tower off, and if the bolt wont come out, you have to punch it out anyway, and cant to that with the tower still on the tranny.
