IMS shaft not aligning to case bore 2000S

Was this change an attempt to deal with the start of the IMS bearing failures?

No, cost savings and to reduce chain noise.

So I haven't had time to get back to my engine since I was on vaca the past week, but looking at the JFP link the 2 drive "sprockets" in the illustration look very different. One company had them listed as "sprocket style" and "paddle style" when I was purchasing the used crank. Will the updated style even fit a dual row chain on it?

Here are photos of the 2 cranks I have (sorry they are just photos I took documenting the teardown/rebuild):

original setup - dual chain sprocket on right side of crank



Here is the replacement crank - sprockets on left - look the same with 2 sprockets rather than the almost timing belt pulley look of the tooth type chain in the pelican link
