Exclamation Drive Gears Misaligned

While rebuilding my chaincase before the snow hits, I checked my gear alignment and noticed the bottom gear is significantly pushed "in" [towards the engine]. The chain had been falling off a lot, and I'm assuming it was due to this in addition to a few broken chain links. The bottom [drive] gear is misaligned around 1/8" to 3/16".
Should I shim it? Stock gearing.
Or, could it be that my drive shaft is pushed too far the other way due to bearing replacement on the opposite side? Ugh
ANY help or input greatly appreciated.

If the speedo side bearing is with the end of the shaft, the only other reason for the sprockets being out of alignment is that the bottom one is on backwards.
The shoulder should be towards the bearing.

The lock collar is on the inside and bearing is flush on the speedo side!

Nope, I definetly have the sprocket facing the right way, shoulder towards the bearing. I guess I'll try prying the shaft over and sliding the collar farther over to the speedo side. I replaced that speedo bearing last season, so it could well be the the shaft is just slightly out of alignment.

Make sure that the bearing in the case is in the right way too, it's supposed to have the shoulder/cam facing the sprocket.

Yeah, every bearing and whatnot is correct. If I shim it, the shim would be around .156", around 5/32".

If all is correct they should be in line! Even is the tunnel had been flexed, the lock collar on the one side and then as you tighten the sprocket it would pull it back! I would pull the shaft and see why! I have twisted the splines right off my Pantera!
