JP is my personal go to for parts

Yes, they will fit. I’ve installed on 4 bikes. While down, install Rocker Lockers to eliminate rocker shaft tick. View videos on internet to confirm.

only thing that I can say about this product is that it would have been nice to have the gaskets marked with correct postioning. ie this side up or down or towards front or rear of bike. For the first time user this would have been useful. Did not use the air breather assembly gaskets and parts. Bought the new upgraded from HD (easier than trying to scrape off all the gaskets)
