I have a set that I had made in the 80's.
I had an old set that looked just like those and had new ones made off that pattern, a copy but nicer. I had the collector tuck up a little higher at the bottom of the fender. You have to notch or remove the splash shield to install. They are like new and have been jet hot coated and never ran. I'm looking for $600 if your interested I can shoot some pictures out tonight.
