Most of the ones I found locally were formed by bending the hook to make the eyelets and only support 75 lbs. Be sure to get the cast type. The local Fastenal did have the correct kind. And McMaster ships very quickly. I didn't check the big box stores. Anyone have luck finding them there?

but thats at least 150lbs with the set of 2 however thats without dynamic loads...

That is true, however the specified part is rated at 500 lbs. To me, 75 lbs is not similar to 500. And when you add up to 20 lbs of bumpers and a battery, you are approaching 150 lbs. There is nothing worse than driving around a strange city looking for an open Graingers so that you can pass an inspection. However, you can avoid the whole eyelets thing by having structural members on each side of the robot near the balance point that they can wrap a rope around as per the rules.
