Those 2 boards look the same to me, do they have different part numbers?
There's a few numbers on the boards, and I'm not sure which one of those is the part number...but all but one is differet.
The spot on the cracked board where the blue wire went looks like something was soldered to it at one time, you sure that wire didn't come loose or something?
Yeah that's where I de-soldered the blue wire.
To be honest there are probably no traces in the area where that crack is and you could just use the old board as is (just check for traces going through there 1st. Unless you broke it removing it it should still function.
No, a few traces on the bottom are severed.
Take a look.
