gagues, and diamond vinyl...
 

Hi, I have a few questions about aftermarket gagues...
what size autometer gague fits in the dash, I guess 5" for the tach and speedo, and 2"5/8 for the others? can anyone confirm this? I just dont want to buy the wrong things.

and the diamond vinyl kits...
are they difficult to install? my car has tan and its not in the best shape so I was looking at buying the black, any sugestions on where has the best/cheapest?

thanks
