I went online to see if there was supposed to be a riser plate as my accelerator pump was rubbing on the manifold. I found that there was and had gotten the original part number.The part is out of production. I checked all around and only West Coast Classic Cougar had it. It was black phenolic plastic like the original, not tan, and matched the shape of the original. It was worth the money to have it look original as opposed to getting a riser from Holley that did not match. Perfect fit.
