The chain backing bracket was a common problem with the reverse chaincase. It probably failed causing the chain to break.
I think they wear if the bolt comes loose and then breaks, the updated part has a new piece welded on. For some reason my bracket is twice as much as yours although yours tripled in price also.
Toe in of your rails would not cause your chain to break, it could only be toed in so much unless your front cross brace is super bent, and only at the front. I doubt you could have bent the front arm holding the shock but I suppose it's possible.
Loosen your track fully and see how it turns. If it is still to hard you did something wrong. Check the brake and rotor and make sure it isn't holding up there. If its still too tight take the chaincase cover off and have a look. A new chain can be pretty tight, did you do the proper procedure for the auto chain adjuster. Pic included without auto adjuster installed yet. and new backing bracket.
