The hole had to be drilled out, but I am not running a stock front end link, so I had to drill it out for a M12 bolt.
The position of the front end link connection is 1" lower than stock, but with the adjustable links I have, was able to accommodate this. They could change that for the SHO and hole size would be good.
Will find out on the rear nut.
Update - nut is not the right size, but we had 2 available.
Also, the front coilover sit closer to the wheel by 1/4" and I had to add my 1/4" spacer to to the front to clear my 275/45-20's. Would need to change wheel offset to fix without spacers.
