I picked up a set of glass tin for my -6, so the OEM tin I was running is for sale.
There is no rust or pitting on the tin, and it was powder coated satin/matte black. It was modified/trimmed to fit the oil line for pressure fed tensioners, and was also modified previously to work with an MFI engine. (Front tin has a pipe brazed into it for the heated air snorkel, and the back tin piece was somewhat butchered to allow a 911 MFI belt cover tin piece to be riveted on.)
All in all, it's a nice set of tin, despite the minor modifications. Easily corrected by a fabricator if desired. The powder coating was done 4 years ago, so there are some minor surface imperfections, but nothing visible once the tin is actually installed. I'd say it's a solid 8.5/10.
Looking to get $550 plus shipping CONUS for the tin. Pictures to come this evening when I get home from work.
