Alright got the replacement.
Now how do I get the old one off?
Try to turn bolt and the whole damn thing turns.

Also, I just have to line up the two points first and do the same when putting new one on correct?

 

New, on yes, best I remember they go towards themselves, exactly on a line from the center of each shaft.

One way to stop rotation is to pull the dust plate back at bell-housing, and fit something against one of the starter teeth there. Yes, booger that. I didn't even torque my last crank pulley, I just slammed the 16 inch handle hard as I could with my palm, then did that again a few days later.. With the plate off there is a place somewhere to fit say a 1/2 inch drive 3/4 socket, against the bell-housing and a starter tooth, is all I've got. Even wood, or a screwdriver could hold it.

 

I got it and it's on a stand, so no flywheel; thanks for the input anyway lol
There is a pin and spring I suppose is to keep it from coming loose.
Got it torqued to 60 ftlbs
Huge difference from the old one. Tho pretty sure I could have gotten away just replacing the chain
