its still pretty close in your pics. depending on how much flex your motor mounts have and how hard you run it(fwd-R-fwd-R-fwd-R-fwd in a mudhole), you may want to give it a little more room.
I think I'm going to simply cut that sub frame brace and weld it a little further forward. I believe that will give me the clearance I need and maintain the strength, if any, it adds.
