About to install the james duff brake booster in the 72. couple of questions:

The stiffener plate goes between the blue mounting bracket and firewall on the passenger side?

The four mounting bolts are already on the truck and they go thru the firewall into the frame underneath the dash?

Anything else i need to know?

Stiffener plate goes on the passenger side INSIDE the bracket NOT between the bracket and firewall.

Click on "3707 Brake Power Booster" under "Adapters".

Also, check to make sure those four bolts are long enough to use all the threads in the firewall. You don't want to catch just a few threads and then strip them out when you tighten them down.
