I have looked multiple places. There seems to be a break between 55-56 and 58-59 I did manage to find 1957 1/2 ton short bed line set. Can anyone direct me to an original style complete line set for a 57 longbed 3/4 ton truck? Any help is appreciated.
Thank you

What's the difference between a 100 and a 150? Classic Tube lists a set for a shortbed GMC truck that doesn't distinguish between 100, 150, etc. That makes me think that there's no difference in the lines so the Inline Tube set for a '57 1/2 ton longbed will likely work.
Do you have your old lines? Inline Tube will make new ones with your old ones as templates. You can, too.

Thats the thing. I don't know the difference. The frame is narrower on a 3/4 ton. I assume there is a difference because the other years I mentioned make a distinction between 1/2 and 3/4.

1957 GMC 102 (1/2 ton long bed) and 152 (3/4 ton long bed used different brake slave cylinders. I don't know if the fittings were the same size or not.
The GMC Master Parts Book covering 1955.2 through 1960 did not list any metal brake lines for trucks other than bulk tubing listed below. NSTXY are model year designation (N=60, S=59 & 59, T=57, X=56, Y=55.2). 10, 15, 25 etc are models where 10 = 1/2 ton, 15 = 3/4 ton, 25 = 1 ton etc. Looks like they expected the mechanics to bend their own. "CTL" on the right side is an abbreviation for "Cut To Length".
By the way, there were no "short bed" 3/4 ton 55.2-59 GMCs, so don't expect a short bed GMC kit to fit.
