4" to 4.5" Bolt Pattern on a 7 1/4" Rear?

I found this thread while searching for answers to this exact same problem and wanted to let anyone know that I too contacted Moser and spoke with Aaron. He confirmed they will still do this "plug and re-drill" the axle Hub and Brake drum in order to get the 5/4.50 bolt pattern needed to get my 69 Dart back on the road again with updated wheels and front Willwood Disc Brakes! Thanks to shhnappa for starting this thread and to all those suggestions. If shhnappa has a an update on how all that worked out in 2008, I would really like to hear about it.
