sorry. my explanation came across wrong. of course i meant just get the analog cluster from the dohc or sohc, the actual 'Heads Up Display' is universal - but wont work with the analog custer. basically its just a fix to have MPH without having to wire up a speedo, or pay out the butt for a repaired/refurb digi cluster.
(btw. your HUD is probably not broken, its the ribbon circuit board on the back of the digi clusters that usually burn out, when i replaced mine the first time, the HUD was fine, the cluster was bad)
