i have a manual,base 99 cavy, with no tach. i found a cluster with a tach in it. the owner says that it is from a 99 cavy, and it is a manual transmission. the only difference that i can see is that the speedometer goes up to 180 and mine goes up to 120. i wrote him and he says that it won't fit. i don;t know if he doesn't know what he is talking about, and doesn't want to risk the return or if he knows that it will not fit. if anyone has any insight then a reply would be awesome.
