Not sure what brand but they were the style that had two flats instead of one flat on the bolt. this give a lot less thread area. I Had more of them in the parts bin I threw them all away. I think I bought them at NAPA. I should have used cleaned up original bolts with one flat. The poly bushing just came apart from foot braking it. They are stiff but they are junk. I will never use anything for bushings but rubber
