Thanks for the pictures... very helpful. I think that the F20C mounts are about 1-2" further forward than SR's from what I have seen in pictures; tough to say for sure because it could also depend on how close you run the either engine to the firewall. I may just end up doing the cradle setup, but I would like to try the bridge mount design for fun, I have a lot of manufacturing capabilities thanks to the place where I work (3D CAD, Laser, press brake, etc.). I am very excited to get the engine and transmission all mounted up; that will be a great milestone in the project.
