Slippery does still make them but I had to ask a dealer to look it up & order for me, tough to find locally. Beware if you go that route aftermarket bars are wider & will stretch the fabric at the ends of the bars & wear the stitching loose over time, mine was ripped open after only 2 seasons - was a great cover but you’d think they would have thought of that!
I like the look of the Zirb-Tech’s, thanks for the link.
