I'd contact Keystone. I've owned a couple Keystone products. They have always been helpful. Our first new RV was a Keystone Springdale. At PDI the table was as bowed as a sway back mule. The part was ordered that day. We went home (about 150 miles) and Keystone just shipped anew table to the house. Didn't want the old one back.
When the outdoor shower shot a knob across Topsail Hill. They again sent the part and I had it installed myself (my choice).
My point being, from my experience Keystone customer support has always been very responsive.
