I have successfully swapped 95 OP gauge internals into my 2003 cluster. You might possibly
be able to swap the temp gauge guts in a similar way - I don't know for sure because I haven't tried it.
The 2003 tach should read correctly if the grounds are connected correctly because it's the combination of ground wires that determines if the 96~2003 tach is calibrated for 4, 6 or 8 cylinders.
