I feel stupid asking this, I need to know the easiest way to get the timing chain guide screw. I took on the task of changing the head gasket on my 2004 Chevy Trailblazer V6 4.5L. I'm down to this last bolt and we will be able to get to the gasket. I say we because I have to get my brother to help me (I'm a amputee).

Here is a diagram of the timing chain and have marked which one is stripped.

We've been working on this for a month. He can only help me on Tuesdays.

I gladly take any advise. I'm working with limited tools also. Thanks in advance....
