I have some damaged turbo bolts (13mm head bolts) that I want to replace, they are the stock black inconel hex-head bolts that go on the turbine housing exit flange and connect the downpipe (or precat) to the turbo. I need 4 of them in gently used, good condition. Please email me if you have some. I just don't want to re-use the old ones with slightly damaged threads or rounded heads. If you have more too, that's ok, but I need at least 4 of them.
