This is something I heard about a long time ago and I keep seriously considering doing it but have never pulled the trigger. Well in the next couple of weeks all of the drivetrain will be removed from my Yukon so now is as good of a time as any. I was going to order the 12 S10 metal cups, 12 S10 Blazer body mounts, and 12 S10 retainers. My question is the thread I read said to leave the core support alone and in other parts of the thread it said to change the mounts there as well that it would tighten up the gap between the grille and the bumpers. I just want to double check that when I order the 12 metal cups, retainers, and Blazer body mounts from LMC I will have what I need aside from the nuts and bolts I will source locally.
