WELL I COMES WITH INSTALL INSTRUCTIONS, BUT IF YOU DO A SERCH FOR MOSER 12BOLT INSTALATION IT WILL GIVE YOU A FEW OPTIONS, I THING IS IS THE ONES THAT HAS A WEB PAGE THAT STARTS WITH www.FBODY.SOMTHING. JUST INSTALLED MINE LAST WEEK MYSELF SO IF YOU HAVE ANY QUESTIONS JUST DROP A PM.
its pretty straight forward....did mine in about 1-2 hours by myself mostly. first time i have even swapped a rear. one of the GM HIGHTECH PERFORMANCE issues had a article on installing a Strange 12bolt. check their website. it was a recent issue.
