Those with summit headers.

I remember having fitment issues when I installed them last year. I had to Jack the engine up half an inch to get the necessary clearance. I installed washers then caught 2 threads of the engine mount(driver side). As I attempted to tighten it, it just span. I'm looking for the same mount but with longer threads. Has anyone done this? I believe pick ups use the same mount with longer threads. If this is the case anyone know which one?
