Trying to figure out what the little rubber shields are that are attached to riveted strips in the engine bay of my 69 S2 coupe are called and if possible the part number.

They are riveted to the cross member just in front of the heater box unit. In the photo you can see the rubber just to left and right of the heater fan unit. They are meant to seal that area from tire splash. thank you!

 

That's a "Mud Shield Rubber" I believe part number BD20434. As I recall Moss sells you a roll of it and you cut the lengths to fit, including punching holes for the rivets. If you have them, best to save the old ones to use as templates.

 

Yes, that's it exactly. The metal strips are in tough shape, so using that part number, I found the kit to replace all. Thank you!
