[cobra09]

Hi all,
I am a newbee here and need some advice or help. I need install wiper motor and linkage as there are none on my car. Same as the park brake handle and cables. How difficult is it to install these? I am more than a little concerned about cutting holes in fiberglass for wipers. This car is already painted and really don't want to mess up the paint or glass. Is there somewhere I can get install instructions for these two installs? Or would I be better off having someone do the work? Any suggestions in Houston area for shops in the know on Cobra's? Any idea of costs for having a shop do the work?
