More Hardware Difficulties

I swung into Lowes after work and picked up some 1/2-13 x 4.5" bolts for my shackles because the 1/2-20 x 5" ones with the kit are too long. Well, the 4/5's didn't have enough thread engagement. So, I need 4.75", which Lowes doesn't carry. Luckily, we have both a Fastenal and a Grainger in town. If only I had realized that they were the wrong size before both stores closed. Instead of doing a nice shackle drop, I am now watching Contact. I always turn it off right before she finds out that the alien has taken the form of her dad. Worst ending ever.
