Unhappy [Q] Is there a MJ4 4.3 i can upgrade to from 4.1.1 Bell?

Is there a stock 4.3 rom with the MJ4 bootloader for bell floating around or something close to it? I find there is no love for the canadian variants here Also tried getting the regular MK6 from sammymobile and it says i need to be logged on to the forums even though im already logged on.
Bell SGS3 rooted, Bell Note 2 4.3 rooted
