Totally confused.

It's all good. You will find if you take the time, ask the right questions and have a lot of patience, these guys here will overload your mind with knowledge. I too was used to easy builds, but I'm learnin' that my A-body will be a bit more of a challenge, but will be far greater of a feeling of accomplishment when I'm done. Cheers!
Oh, and welcome to FABO and the world of A-bodies!
