Not sure they will fit, but my 1977 Trillium
came with an A & E transawn 2000 awning, and I needed parts for it. A & E stopped making them decades ago. But.... they licensed the design to a south African company, who still makes them! Now its called an eezi awn 2000. And they have a stocking distributor in Utah. I had to buy tension rods.
I have no idea what your awning looks like, nor what the parts look like either. But some designs have survived under new ownership. Good luck with the hunt.
