And those extra 180, 90, and 90 degree turns *REALLY* feel wrong when
you're doing them! If you're used to the feel of the metal it's VERY
scary and feels like you're about to do some serious damage as the
metal is stretching. I've never yet had a problem when following the
procedures in the Bentley, but I cringe every time I have to do one of
those stretch bolts. They just feel wrong.
