I used standard (non stainless) from The Right Stuff out of Westerville Ohio. I would give them a 4.5/5 star rating. The rear axle line was a little long and I had to tweak it to make it look respectable. The fuel line was similar, specifically where it crosses over near the power steering slave cylinder bracket. Tweaking was carefully closing down or opening up bends without kinking the line. The other lines had no issues. I think we really need to here from someone that does a couple a year and has experience from different suppliers. If we don’t get that response I would say to use them, realizing that you should expect that, like most reproductions, tweaking should be expected.
