Gauges, Switches and Cruise Control

Hi guy's,
 
A couple of questions I have recently been pondering.
 
After writing off my 94 NA I recently purchased a 93 Turbo. The NA was to be the basis of a project and as such I have a plethora of parts. One being a custom gauge set from Speedhut. Being quite expensive I'd rather use them if possible. Is there much of an issue installing an NA cluster into a turbo? Not fussed about the turbo gauge as I have some Defi Gauges to install into a dash cluster.
 
Secondly, I REALLY miss my cruise control!! Is it possible to have a stock type cruise control installed?
 
Lastly, just because I'm lazy, has anyone used an auto window switch such as the drivers window in the passenger side and on the the drivers side passenger window switch?
