I just looked at the pics and I may be mistaken but the one of the 8.8 from the drivers side looked like you had the caliper on the wrong side. If I am seeing it right it appears that the bleeder screw is on the bottom. If that is the case, it is on the wrong side and you will never get your brakes bleed all the way. Just something for you to look at. Other than that, it looks great and you will be happy with that for a rear end.
