Intercooler requires the firewall cut!
Cant imagine the grief of working that last cylinder in the hole. I HATE the modern trucks for that too!
Rob, my mounts are welded to the frame the same as your's is mocked up. The torque constantly twists the frame and causes the top rail to crack next to the weld. It has also broken top to bottom and across the bottom rail. Be sure to beef the frame entirely, from K member to at least the first crossmem.
Plastic trucks suck...
Iron trucks rule...
