Just did mine over the weekend.
That Driver side starter bolt is a pain, but I just used a deep socket 14mm, 3 inch extension and my ratchet.
Feel for the bolt with one hand, push wires aside and place the deep socket on the bolt real good. then attach the extension, then attach the ratchet. I left them all in place after I removed the old starter and just lined up the new starter with the driver side bolt. I didnt have to fish around again to mount the new starter.
and this is invaluable to remove the manifold bolts/nuts. just loosen them with the 12mm and use this after to take them out. use this also for resintall.
Looking back, it is more intimidating than it is.
for taller/bigger dudes, I think taking the hood off would help with the install.
