I tried to do both sides at once. The youtuber I watched did it that way and his was apparently easy. He must have gotten lucky. I'll start with dkr's suggestions. If that doesn't work, I'll make a trip to Harbor Freight and try the stuff Diesel911 suggested. Good call on drilling through and using a nut and bolt. I'm less worried about destroying the threads in the aluminum if things go pear shaped.
