What a great idea! None of my vehicles have loops on the frame to tie my canoe bow and stern lines to when carrying my canoe on the roof rack. These provided the perfect solution. Remove two bolts from the top of the radiator, and bolt these on... a perfect place to tie off those lines.
The only reason I did not give them a 10 is that they dry-rotted after about 2 years. Cheap enough to replace, but they were not exposed to sunlight so why did they fail?
