Silicone will withstand the heat. There is silicone tube in different sizes.
After you find the size between the fins, cut to length and place the tubes between the fins. IF the tubes WON’T hold their roundness (well enough)
Get a tube of silicone and put a bit inside the tubes and let it set for at least a day. Re install your rope (now its rope in places anyway) and your done.
I use to modify certain boxer engines in the late 70s early 80s for aviation use. Very reliable and super easy to turbo for high altitude and add a blower for rapid low altitude boost. Same principal as the mighty Merlin.
I used modified fin stabilizers because of crack that were developing at the base of the fins. Those cracks, NEVER formed on normally asperated or even with a turbo, but with a blower (belt driven) at low altitude, there is a LOT of pressure when detonation occurs. Those fins RATTLED and started to fracture.
At the time silicone was pretty new to the automotive world, old news in the aviation world and still VERY expensive. It worked and stopped ALL the issues that design was having. I worked with a guy named Smokey Yunick. Smart guy...
Well that was a long one.. Brought back a memory or two..
Silicone, man oh man the stuff it’s used for. Carol Doda, business woman of the year. least invested for the largest return.. ;-)
