Jerry - Since it is off a Concord - it is for the AMC 6 cyl. : 1981 - 1986 . In 1987 they went to the 4.o wide cyl. block and used the 4.0 alum. valve cover. 4wdhardware.com has these as well .

A friend of mine has a Clifford aluminum valve cover for an AMC 6, but I don't know what year engines it might fit. He said it was for a Concord. I'd like to fit it onto one of my early Gremlins. Anyone ever used one on their early 232 ort 258 ? He wants $75 for it, and I want it to spruce up my engine compartment. Thanks for any help, Jerry in Virginia satisfying weekend in North Carolina
