94' buick skylark EGR Valve

My Skylark EGR Valve needs to be replaced...according to the codes 75/76/77 (EGR Solenoid malfunction). I bought the Hanes manual for a 94' buick skylark, but the EGR valve in the book look very diffrent from what in my car. It's a single unit with 3 solenoid mounted on top and a rib pipe hooking on the bottom, but the manual have the one that looks like a standard EGR valve.

My question is: Have any one change one of these lately?

Thanks,
Rap
