A: Cherokees and Comanches. The 4 cyl one is probably the same as well, but may not have a cam button (too lazy to open up the core one I have now) From: Todd Tomason <jayscore@xxxxxxxxxxxxx> Subject: 4.0 Timing Cover on 258 To: AMC List <mail@xxxxxxxxxxxx> Message-id: <200507220632.43659.jayscore@xxxxxxxxxxxxx> The other day Jim Blair mentioned using a 4.0 timing cover and cam button on a 258 to prevent cam walk. He mentioned that the covers from the early 4.0's (87-90) will fit. What were this engines used in? Will I find one in an early Cherokee? I'm going to try and find one at the local Pick and Pull tomorrow. Thanks, Todd
