Sorry to jack your thread, but I was wondering if a Si Cluster w/ tach is a direct swap from standard cluster w/o tach. I am assuming it is...
Also, are the Cluster's interchangeable between 88-91? The Shape of the "Cluster Hood" seems to be dirfferent, more round on the newer ones, but can you use say an 88 cluster on a 91 dash if you use the 88 hood as well?
