If you have to do motor mounts go with merchants set up and be done with it. Remember that exhaust sticking out that far will greatly exagerate the engines movement.
I had a set of bolted stockers so they went in today, along with Kodiac manifolds/up pipes, and a looser converter that ill try out. The drivers side was two pieces, and the pass was twisted pretty good.
I have no idea Ben! I kinda wish it were something obvious like that. At least then I'd have known why. But no! All mounts (engine & trans) are fully in tact! Ugh.
