Does anyone know the brake line sizes for a 76 C10?

[straight6chevyguy]

Hello all, I'm looking for the size of the my rear brake line the one that runs along the passenger side fuel tank.
Mine line isn't leaking but there's a really rusty spot that's pretty deeply pitted, bad enough that I don't really feel safe running it.
I could just buy a premade line but was thinking maybe just make my own but have no clue what size line or fittings to buy.

I'm currently working on replacing all the lines on my 81 while I have easy access. Not sure if it's the same as your 76, but on my 81 the rear line from the proportioning valve to the rear axle hose is 1/4" line. So is the line from the master to the prop valve. The front lines are all 3/16". I'm not sure what the lines are on the rear axle itself as I haven't pulled those off yet

Fronts should be 3/16, front to rear should be 1/4 all the way and thru the rear soft line, back to 3/16 from the rear soft line distribution block to each wheel cylinder across the rear axle…
I would suggest getting NiCop brake line for the splice. It doesn’t rust and it’s really easy to work with.
