Car won't crank, Guage lights flash, and how do I pull my starter?

I think you'll find there is a straight shot at that upper bolt so no universal req'd. With any luck the lower will be a stud with nut on it. Stud supports and aligns that heavy *** starter. Makes upper bolt easier less likely to get cross threaded. Most opt for the modern high torque mini starter as replacement. I will too someday, when my last good used starter fails.
You might first lower the starter and move it to where you can better access its wire connections.
It helps me mentally to know there are some that are a heck of a lot more difficult than this one.
