Hey guys. Just wanted to share my approach in case it helps someone who's not as handy with welding in such.. or just in a hurry.
Basically, I tried 3 separate universal lock plate pullers in my local store.. none had this size, so I came to this thread and figured I was done for the day because I didn't have the tools to make my own puller. Anyway, I kept thinking for a few, went down to my local hardware store and picked up a hefty washer.. not saying I recommend this, and it's definitely tool abuse, but here's what I came up with, and it got me out of a pinch. I just snugged two sockets under the big washer and used those to push the plate back.
This photo was from before I realized I needed a larger washer to get clearance for the snap ring.. but you get the idea. I just used the nut that held the steering wheel on to apply the pressure.
