AC Pipe Insulation

Can anyone tell me where to find the ac pipe insulation that is found the the ac line of a 1978 Corvette.  The insulation appears to be some type of flexable black dope compound. 

You could use this product??It's pipe insulation that is flexable? Ace Hardware is the place for me..

Thanks for the reply.  I assume you did not have any problems with the foam insulation melting due to how close the pipe is to the exhaust manifold?

Try Corvette Central part # 452331 it is a black rubber type insulation.

Sorry Scott, my 76 the AC lines run along the upper inner wheel well away from the exhaust headers, around the coolant recovery tank and down behind the wheel well to the VIR eliminator.
