If you are planning to switch to a 9" you need to seriously consider a full floating hub rear. Moser sells a complete 9" rear minus the center section for $879 in any width you need. If you are not familiar with what a floating hub is do a search and you will find a good deal of information. I'm sure DSE has provisions for welding their brackets on your housing. Here's a pic of my Moser 9" floater.
