I had a leak from the oil feed line, I think the gasket was bad. The nuts was tight but it still leaked an when I pulled the turbo today the gasket was all bent up. I was going to buy new gaskets but I figured go stainless lines. My question is the stainless line from ebay are they bolt on or will I run into problems? Like the ones on ebay look different compared to the feed line with the big bolt & banjo fitting on the block of the 3sgte. Any use these before?

just buy a brand new OEM gasket.

Yea I did just that a few minutes ago
