I have a 1988 GMC C6500 with a 427ci engine. The power steering gear was leaking out of the bipod shaft very badly. I was in dire need of a truck so today I removed the bipod arm, removed the snap ring, removed the boot, washer and old gasket. The new parts fit perfectly. Thanks to this kit I didn't have to remake the whole box. My steering gear is a 710ml Saginaw I think.
