You can ask............but I would just pull one of the others on the exhaust manifold and see. I believe outer ends are the same and centers are different.

EDIT: Who knows............they may all be loose and ready to back out.

But if you are afraid to tackle even basic repairs, you might just want to park the car. These old cars can and do break.............that is half the fun...........fixing them.

Not afraid of any repair just don’t want to start anything in 95 degree weather. That said you were correct every bolt was loose.

Length is 2 1/4 (quantity 8) and 2 3/4 (quantity 4) with a NO AC car. For AC cars there is a special stud in lieu of one of the long bolts. All the vendors carry them.
