That one came from John Keady who got it from Brett for me way back when. At that time you could only get the 168mm from LFP. But the one in the pic came with LFP stamped in the blade. I’m guessing the 170 was about to become available through LFP around the time I got mine. Mine is for a GT500 not sure if it’s the same for your application. Also came with this shiny spacer.
I am looking to purchase the piece of firewall insulation that some Lightnings came with. The piece behind the supercharger and it needs to be in good shape (no junk). PM me here please and I'm a buyer now.
