The P/S bracket requires the 1/4 inch longer bolts.
The other side gets the shorter ones.
When no P/S pump is on the engine, all 4 bolts are the same. Do not install the longer bolts on the P/S side without the triangular bracket as they will drive into the cylinder and crack it!
You were right and smart, to ask.
Thank you so much! I wonder maybe the previous owner didn't have power steering and then when he put on the power steering pump he just used the original shorter bolts.
