US Car Tool Subframe Connectors

I am getting ready to install the frame connectors from US Car Tool. I have just replaced the floor pans (front and rear) in my Dart and was surprised when test fitting, about the large gap between the pan and the connector. I thought was something I did (might still be) but decided to reread the directions (the long version) and learned there can be a 1+ inch gap, in some areas. Is there anyone who installed these connectors that has pictures I can look at? Maybe during and after install pics and what did you do to deal with the gap? Thanks.
