You are deffinately in the right place for info on that subject as there are many that have done at least one sas and several in the works. Its not really a hard project, just rather time consuming to cut all the old ifs garbage off and grind it all smooth. Of course if you have a snag along the way we all would be here to answer you with advice and experience quickly.
