Review on DORMAN 65277 Copper Oil Drain Plug Gasket, Double Pack by Manuel Gfx

Arrived in a box with other items when ordering. The packaging for this fell apart in the box and one must have slipped out of the box as I only had one loose washer in the box. (The box wasn't fully taped so the top and bottom could come loose and the washer slip through) I bought these to make an antidote mod on my 2004 Z06. I used a shim I had but it almost didn't matter (t56 gearbox with MGW derailleur). I heard that both washers are perfect. I wish I had them both
