Scarebird disc conversion

I thought I read somewhere about re-drilling the rotors to the small bolt pattern. That was what I was hoping to do if I go with Scarebird.

Parts are parts as far as I am concerned. The calipers & rotors will be hidden under my rims & it is not like they have GM engraved in big letters on them. My car is going to be a driver & I am upgrading certain areas for safety so I have no plans on winning any restoration awards. In today's economy with what Mopar parts cost I need to save money anywhere possible or the car will sit for years while I save up. Just my 2 cents.
