On the big flare parts I just dilled holes for the bottom of the flare. The flare parts are extremly easy to install.
Its the little peices on the doors that are hard to get straight. I had to drill a few holes on each side to get it right. I didn't have to install those little clips behind the flares. They wern't needed. I might have to intall maybe two of them, just to get the top of the flare pulled in closer to the body but that it.

I'm not sure on the paint, I bought some duplicolor paint but it was alittle off, so I have to keep looking.
I too need to repaint the flares.
