Those instructions from SuperPerformance are what I got with the seal kit with the Blue silicone side seals. The Orange silicone side seals seemed softer than the Blue ones, and I had to start with more of the seal below the retainer. Not a big deal, you just may have to slide the retainer into the block a few times to get the side seals in correctly. These fluoroelastomer rear main seals have worked good for me, just takes a bit more time installing them.
