s14 tension rod bolt, the 4" one, grade 8.8 bolt safe to use? Had to buy because it did not come with the rods and I had to cut the oem one off. The original didn't have any stamped number and the store I went to didn't have anything tougher. Every other store was closed that sunday evening. I can definately get under there with a tougher grade bolt now but just wondering if it's even needed as 8.8 seems pretty tough, but what do I know.
