Brake Line vendors?

[TexasLS1]

Does anyone sell individual steel brake line replacements for our trucks? All I can find are complete kits...

Here's some background - I'm doing the drop on the front, and adding longer brake hoses for the calipers. I cannot get the driver side fitting loose from the hose, and I know I'm going to damage the fitting to get it off. I dont' think I can go to the local parts store bc the fittings on the driver side steel line are different sizes, and I really don't want to have to buy a complete set of steel lines just to replace one. Any ideas?? It's the steel line that runs from the rubber hose, back over the top of the crossmember toward the cab, where it joins a "T" junction block, overall it's about 18" long IIRC (I can add pics later if necessary).

I may have to buy the whole kit, or maybe piece it together at the local parts house if they have the right fittings, but hoping there's another solution out there...
