Got down on my 70 year old hiney and looked through the grills and all I see
is about 2/5 of the grill is solid. The passenger side has a square hole in that solid part, but I see no tabs. Driver side grill pretty much the same. I must not be looking in the right place.

I thought let me see if I can get at the tabs from under the hood, no cigar there either. Can one of you lead me by the hand and tell me where to look?

Noting that 2/5 of the grill is solid, not so sure painting it without taping off those solid parts so the whole thing looks like a grill would look so good. But if I can find a way to tape off the bottom of the solid squares it should look pretty nice....

Can I see these tabs of which you speak from the front of those grills?

Thanks Popeye
