I did the same with mine. Filled all the holes. Best looking grill IMO. No chrome pieces around mine at all though, even though I do thing the big chrome squares look kinda cool. I just have the stainless bezels around the headlights.
EDIT: May as well clarify that mine's a '78 and had that standard grill when I bought it. After running an SSII sport grill for a couple of years I decided to go with the earlier style. Found what I guess was a '75 front piece in really good condition at a local 'yard and went to work on it. This was back in the mid '90s. No regrets.
