what darthpup says, but with this variation - use the dremel tool to cut a
slot in the screw and use a screwdriver to extract. AeroKroil is great for
helping unseize bolts, spray with Kroil and wait a few hours - repeat,
then
remove. If it is seized solid, use a left hand drill - first you need to
get a pilot hole so you dont' keep slipping into the aluminum, then drill
out with the LH drill - usually the LH drill will at some point bind and
unscrew the thing for you - the bolt is not hardened. using a air driven
right angle drill may help. Be prepared to helicoil the hole if you mess
it
up. Using one bolt will be a disaster waiting to happen, don't do it. if
you are close to needing a clutch, this is a great time to do the clutch
job
and drill out the bolt while you have it apart (by the way, I have a
spare
bell housing if you would like a replacement)
