The one on there is cracked by the number 3 cyl. on the front on the engine near the radiator. i Have been all over the internet looking for it i just cant find any that im shure that will fit my car. Ones mite fit but its for an 2004 im not shure if it will fit the head or bolts line up etc. Can some one help me out and see if u could find a reasonable priced exhaust manifold that will fit this car and throw me a link. thanks btw im new but grown up around 3800 parents had an 87 buick
