Half shaft Driver's side Bolts...

[A//// Guy]

Oh that is not a fun problem. Im not sure what you can do as far as not pulling the engine. I doubt a drill will fit up there and then you have to tap it all out, which I think would be very difficult with the engine inplace. You could fab up a different bracket bolting to somewhere else but that would be pretty custom.

OR disconnect IC connections and lower the exhaust and the engine enough to maybe get a drill in there at a good angle.

That is one hell of a problem to try and fix with the engine in place. Not sure which route to go....
