Scott verified that his subframe had a similar fit on Grendel's Mullet Camaro. The half height body mounts can not be used at the firewall. I can now move forward with confidence in my setup.
I might keep the subframe wedged as i have it now with the small body mounts in the rear and full height at the firewall. I did the math and the suspension angles will only change by 1.2 degrees.
I am going to move the motor mounts again but I am waiting on my new headers to show up first. You can see how i already lowered the mounts in the pictures below.
I will also add Scotts new extended shock mount to allow a lower ride height.
