Very low use performance manifold, may be no use at all. A/T Engineering product from the 1980s. Made for the 1970s Honda Civic EB 1200. Will not fit CVCC or anything else. Carburetor pattern accepts 32 to 35mm DHLB, DCOF, and Solex C35 PHH side draft Carburetors. I can take more pictures and measurements if you need them before sale. The last picture is for information and example only. This sale is for the manifold only. 

I do not answer fitment questions. Part choice is up to the buyer only. No return for parts ordered incorrectly. Parking on this listing will not do much except possibly raise the price. I DO NOT send or accept offers, eBay's worst idea ever. The price you see today is the "lowest price" you will get here on eBay due to overhead. Also listed locally (CL), I may end the listing at any time if not purchased here. Face to face sale is preferred, that way you can inspect and pay at the same time. I have other early Civic parts listed.
