I have a few quick questions.

1) are there any ways around buying 01 trans lines? I want to go -AN or possibly use something like this if anyone has any experience with it: m.summitracing.com/parts/der-13035

2) do I NEED the checkball fitting or will I be fine without it if I go -AN?

3) does anyone know of a kit or have the sizes needed for the -AN fittings I would use?
