Is the air box gasket still available?

Needing the big foamy type gasket that goes inbetween the fire wall and the air box.
anybody have a part #?
Is this still available?

also, is it just regular urethane sealer used for the top cover to bottom cover?
what did the factory use?
part number?

Use 3m strip caulk. Got that tip from turbonut85.

I actually found them at mikes Montes awhile back. their just like the factory ones and a perfect fit.
I used the 3m strip caulk along the top and sides
