frp top

I have just discovered that the FRP top on my BJ73 is missing nearly all the bolts that secure the rear of it to the sides of the vehicle. I think there are 4 per side and there is only one on the right and none on the left! My question is: should there be a rubber strip between the FRP top...

Looking for a line on a fair to good condition, whole, FRP top for my MWB 70 series truck.
