Question re: installing 964 Rocker kit on 82 911SC

[redstormcoach]

I bought a used set of 964 rockers to go on my 82 911SC and I have a question about the flares.

The flares have two bolts in them. One bolt goes through the hole where the old stock rocker was. The other bolt that is higher up on the flare looks as if i would have to drill a hole in the forward side of the rear fender. Is that what I have to do to get these to fit or is there a different way?

Here are some pics...
