ft,
My crank gear was the same. If the oil pan is still on, carefully mask it with duct tape and anywhere else you don't want metal filings. Drill and tap (I used 5/16 drill and 3/8-24 tap) two holes 180 degrees apart and use your steering wheel puller. Careful as the drill nears the end - you don't need holes in the block or main cap. A masking tape marker on the drill bit at the thickness of the gear is a help. The gear drilled easily, and the job took 20 minutes. There is no room to get a jaw puller behind that gear with the crank installed (I tried modifying one, but with the tips at 1/8" thick they popped before the gear budged.) While I was there, I tapped the crank as well and it makes installing balancers a lot easier.
