LT240 custom tubes

[BerraKode]

Hello!
I have bought a LT240 but need to change to custom tubes because of clearance issues in my Formd T1 case.
I have looked for hours but can't understand what I need to buy. What tubes from this page will fit my LT240, and do I need to buy some extra fittings or something else?

Thank you in advance!!

Best Regards
BK

I have a couple of guesses of what will work but not sure.

4x g1/4 compression fittings

and this tube

Is this all I need or are there some extra fittings I'm missing?
