My 55 truck does not use the rubber straps, but I was planning on using electical arc proofing tape. The material is 30 mil thick and resist fluids and of course electricity to 50000v. I used that stuff to wrap roll bar padding, because it is non-adhesive. It comes in 1.5 to 3 inches wide. A 30 foot roll is probably in the range of $10-$25 dollars.
