what model can i get a gauge cluster from with a 100+ mph to fit in my 84 z28

 

86-89 Camaro. I'd suggest simply swapping in the speedo head and possibly saving yourself some electrical gremlins. You may find the following helpful:

I'd probably also clean and lube the speedo cable. With the cluster removed, pull the cable from its housing. Inspect it for burrs, fraying or breaks. Unscrew the housing from the tranny and shoot brake clean or some other cleaner down the housing until the fluid is clear. Brake clean, for example, will dry rapidly. Button up at the tranny. Clean the cable itself, then put a glob of Napa's Sil-Glyde (mentions speedo lube on the tube) in your palm and run the cable through it as you thread the cable back into the housing. You'll probably have to manipulate the cable a bit to reseat it in the speedo sleeve at the tranny end.
