Hi, Is there a way to put the 03-04 Mach 1 Shaker hood assembly on the 99 Cobra?  From what I can tell, it seems to be the same engine except for the intake.

you are correct, the Intake is the same design, however the Mach 1 intake has provisions for shaker mounting studs that have been cast in to the intake and the Cobra does not have them.  The easiest thing to do is to find a Mach 1  upper intake cover and swap it out "or even try and trade it" for your Cobra one.

Thanks.  I'll see what I can find.  I would doubt a Mach 1 owner would be willing to part with the upper cover.  I know I wouldn't.  Thanks for your time.  I appreciate it.
