300ZX SS Lines

[S-14boy]

I was lookin to do the Z32 Brake swap, and I want to put in the Stainless Steel lines, but my question is that I see people selling lines strickly for the swap. Are those the only lines I can buy or can I just get Z32 lines or 240SX lines, or do they have to be custom to fit??? Also one more question pertaining to the brakes, I see theres a set of R32 Calipers on ebay, they say they're identical to the Z32, Im just wondering if any one has had experience with em, if they really are identical (you know those ebay guys, they might not be totally sure).
