Bill, you have some good points there with the vibration issue. i would like her to last! I still have some time till engine mounting, so i may just take your advice and just that system. the way it is now though the frewall is just as strong as using beams right? do you think structurally the beams are stonger? it'd seem they would be, but the firewall is attached to the beams anyways so it should be just as stong. see this mess of ideas in my head!! haha, thanks again, you have some strong points
