yes still $20 off for NASIOC
button head stainless steel bolts have a rounded head with a allen style key to tighten and lossen them. they just help so they wont snag on anything. regular hex head bolts tend to round off a bit if they get hit with anything so the button head bolt we prefer.
also we do not put any holes in our plates for oil filters or oil drian plugs you do have to take the 5 button bolts out to do the oil change. we have found a ton of different things making there way though the plates that have oil drian plug or oil filter holes in them, sticks, rocks etc.
very easy to instll just remove the 5 factory bolts that hold on the plastic skid pan that is on the car and replace with the skid plate and the bolts supplied.
to get the $20 off just pay pal $132.20 that's $119.95 plus $12.25 shipping to email@example.com
and in the note section just put in your NASIOC user name.
thanks and sorry for the delay in getting back to this thread
