I have a 66 SS convert 4 speed, with a 68 date coded 396. Can someone give me a list of LH side exhaust manifolds I can look for that might fit. I would like one without the smog plugs. I found a list by year, but it really doesn't break down whether is is in a Chevelle, Camaro, Corvette Truck etc. I hate to keep buying, only to find out they won't fit. The one I have now has the smog plugs and is marked 3909878 which doesn't show up on any list I found.
