2x Subframe Bolts - are the tops accessible?

[pierremcalpine]

Hi,
So I did a really dumb thing yesterday. I was trying to chase down a front end creak that only happens when it is 28degC or hotter (just drove the car up from Florida so more relevant of an issue down there than up here in Toronto right now).

I figured I would give the two long subframe bolts and extra tightening to see if they might be causing the creak. Tightened one...check. Tightened the other, crack. Busted. F me.

It's impossible to drill the threaded part out without removing the whole engine cradle/subframe. F me again. Considering just getting someone to weld the subframe to the frame as the car has got over 200k miles on it so if someone has to grind a weld off to remove the engine cradle before the car dies than it's not the end of the world.

So my question is this - is the top of that bolt visible/accessible anywhere so that I could drill it out or turn it from above? I've taken a look from the top but can't see much what with the fuse box, engine mount, air filter, etc in the way. I'm considering pulling all that stuff off to take a look but wondering if I'm wasting my time...
