[TR] Seat rubber straps

[Jim Vassiliadis]

I've got TR5 seats in my 62' TR4 and am in the middle of a semi restore.
I need to replace the rubber straps on my seats but Moss Europe and TRF
don't have them.
What do people use instead?
Here is a link to a photo of them plus my semi restored chassis and tub:

Thankyou to all the TR people who have helped me in the past.
