This would be a T56 issue and not a model
I would assume on F-body it may be easier since on the C5 the MN6 is in the rear and doing this on a floor jack and laying under the car the blood rating is a 3 ( how many areas on my hand that draws blood) and a pissmeoff factor of a 5.

On the C5 being you cannot see the dentent bolt or get a light up there the hardest part is re-installing the bolt for you do NOT want to cross thread or you'd be in big trouble so getting bolt hand started is a must and a bitch.

I would do this without a doubt while trannie is out for then its a 3 minute task.
