Any tips on fitting the US Car Tool Sub Frame connectors?

I put mine in at the angle recommended in order to tie the front and rear front to back frame rails. Mine are shown in photos on my rebuild. I am Old Dart 66, and my rebuild thread is named 65 Dart Revisited, under members restorations. Best of luck on the install. There are some videos on you tube that show the process. Best. Old Dart 66
