Dawg, The subframe connectors will be the last thing going on per the instructions you sent......
"the subframe connectors should be one of the last components installed on your vehicle. Reason being is you want the vehicle settled with all of it’s own final weight. The car’s body is always in constant tension, with forces pushing or pulling within the chassis & body. You want to make sure these forces don’t change after you install the subframe connectors. For example, if you installed subframe connectors before installing the engine and body panels this may result in having misaligned fenders, door panels and/or hood later on.
The car must be in it’s final state before the subframe connectors are installed."
