Brake caliper/hose connection confusion

[ChadW]

I am having a terrible time finding brake hoses (flex) that will work with my setup and be long enough bagged c10 with dropmember..Im running the standard D52 single piston GM caliper..Im confused on what the banjo fitting shape should be/has to be on the flex hose i get..by the looks of my caliper, I have to have the round fitting, not the square or block style...correct?

I bought some 16" universal SS lines and they were no where near long enough do to how they have to route off the caliper. Seen a napa part number 36760 which is a 20" line for a chevy c10 but has a square banjo fitting... any help appreciated...

Here is the napa line https://www.napaonline.com/en/p/UBQ3...cleAddPDP=true
