I have a set of 914/6 tin that was on my car when it had motronic injection. Rich Johnson made these and McMark modified them.
$300 plus shipping from PMB.
I also have the left and right fan block off plates for the shroud to delete heat.
I would like $150 for these factory bits.
I also have a set of ceramic coated 6 headers with O2 bung and a triad dual outlet 6 muffler that I would like to sell.
