A good(emphasis on GOOD) bolt and a long nutwill do just as good a job as a balancer installer.I bought two pieces of grade 8 all thread,one to match sbc and one for bbc,and two nuts for each.Welded a nut on the end of each and use the other nut to push with.Usually use several fender washers,along with the heavy damper washer,all of them greased,to help cut friction.Works fine,not pretty or impressive at all,but I got two balancer installers for under $10
Just a thought for the other tightwads like me!!
