Try JamesW's site here for the granada conversion:http://pwp.clearsource.net/dsigns/james/. Then click on the disc brake topic. Really excellent stuff. I'm in the middle of my swap right now. So far the conversion is going to run about $475.00. A little on the expensive side, but considering I'd have to rebuild the drum brakes also, the cost is very reasonable. Also try a search on www.google.com under granada brakes. There are some links there too. Good luck. Keep us posted.
