Brake Line Questions

[LUV2XCLR8]

The Blazer I Bought From Joe In Cali Had A Piched Line That Was
Leaking, It Is The One That Comes Out Of The Back Bottom Spot
On The Perportioning Valve And Goes Down To The Frame, Then
Connects To Another Line Near The Front Frame Crossmember,
It Is A 4wd, After All The Horror Stories I Have Heard On Lines
Where Do I Get Them From, I Would Like A Stainless Set For All
Four Of The Lines Haveing To Do With The Perportioning Valve,
If You Have Replaced These Please Help, Thanks For Ur Help.
