New Waterpump Hardware slightly Different_Plymouth Duster 360

Hey All. I'm replacing the water pump in my Plymouth Duster 360 and I ordered new hardware from Classic Industries. I attached a link to the bolts I bought below.

When comparing the new bolts to the ones, I realized that two of the new ones are a 1/4" longer but all the rest are identical to the originals.

Attached is a photo. I don't want to put those two in a spot where that extra 1/4" will crack anything. The length of the two new long ones is 5 1/2" where as all four of the old long ones measure 5 1/4".

Two loose washers were also included with the new bolts. They do not account for a full 1/4" tho, and was confused why there wasn't washers for each bolt.

Let me know if anyone has thoughts on if I can use this hardware or not and thanks!
