ellipsoid bracket mounting hardware

[ejs999]

I need the hardware (plastic insert/bolt or screw?) that goes in the 3 squarish holes (per side) to mount the brackets to the car. Looked at realoem.com and did not see anything. Converting from sealed beams in an 87ic.

Thanks

I have the light-to-bracket hardware. I need the bracket-to-car hardware.

Thanks
