If you aren't going to use the hinges and springs then I wouldn't worry to much. We just cut a huge chunk out of ours and haven't had issues with it. Below are a couple of pics (let me know if you need more detail). We just used hood pins and pin it down. Works OK but we are going to switch to a tilt front end this year.
PS... Haven't forgot about your hand throttle pics. Will try to get them soon.
