Last time I hit a starter with any effect was when I was in HS. My buddy had a truck we had to convince to start to go to lunch.
I got the swivel socket and enough extensions to get the socket arm below the car at a reasonable angle. Also my strength seems to be diminished with the positions I'm forced to work at. I'm at the point where I'm ready to put some heat to the bolt. I got some fire proof mat I can cram in there to protect the wires and other nearby parts.
I'm taking a break for a bit as my upper body feels like I slept in the trunk of the car.
Thanks
