Yep looks tight. Might have to see how we go with some heat.

Make up some WMP Chris, short for Weapon of Mass Penetration. It's 50/50 acetone and Carlube ATF-U, it may work with other synthetic ATFs but i've not tried it, doesn't work well with mineral ATFs at all. Acetone can be bought on ebay cheaply or you can steal your wifes nail varnish remover!
Shake well before
each use and keep sealed when not in use to prevent the acetone evaporating. Once shaken it goes pink and frothy, dribble, pour, brush or spray it on to the rusted fastener and leave to soak a few minutes if you can get a spanner on it, in the case of a sheared stud, you may need something like :

Worth its weight in gold, the harder you work it, the harder it grips and works for you. Have even used it with a windy gun (it's rated for that) and the siezed studs stood no chance!
If you go down the stud remover route, don't be tempted by cheaper ones, even the same brand as they don't work anywhere near as well. Also once the WMP has done its work, degrease what you can see of the stud with some acetone or similar before fitting the stud remover.
Be careful if you use heat as there are lots of rubber hoses and wiring around there that aren't obviously visible - don't want to make matters worse!
