I tried using the sharp punch tool/screw extraction method while removing the seal. It immediately moved sideways inside. I was able to use a hook tool to extract the seal out. If anyone is interested, I found a plumbing part at Menard's that can be used for the installation. It is called '4x3 Red Bushing Con, SXH SDR35 SW' in the Plumbing section. Its inside diameter fits nicely over the crank. Once the seal is positioned, it was easy to tap it in. I had to dremel inside a little to make sure the 'tool' sits flush: Thanks to everyone for your input. I lost my clutch alignment tool from the Exedy kit, had to order a new one at O'Reilly's.
