problem with guage assembly

[CoasTek240]

ok.. i just bought a 92 se coupe.
the guage assembly looks really smeared.. so i tried to clean in.. and i realized it looks like it's on the other side?.. is it easy to get beheind that assembly?.. do i need to remove my steering wheel?
does anyone know of a step by step for installing new guages and needles.. or atleast some pictures,, well thanx

if its that bad why dont you order a new piece from a dealer..... or take it off, give it a good cleaning and use some Plexus..... you can get it at most automotive places..... sorry i don't know whats the American equivelant to Canadian Tire.....Autozone? Pep boys?
