I mentioned these spacers in another thread about factory rear swaybar spacers, and just added the third pair today in the front holes.
My solution- 1" round aluminum, 1-1/4" long, 7/16" hole. I'm using a Blazer rear bar currently so M10 x 60 mm bolts (70-80mm? with factory bar), nuts, washers. 3/8" bolts would work too. There are actually six holes in factory control arms, so you could make six pieces and stiffen the arms a little at the front hole location also. Also notice the zip ties to keep the E-brake cable from rubbing the inside of my 17x9 rims. Fancy-eh?
