Well, my truck is a base model, as near as I can tell... but lots of things have been changed over the years so who knows?

I've never noticed any holes or signs of holes in the inside cab roof, which is all metal for me. I don't have the fancy chrome trim tho'.

I will have to poke around and see if I can find where the original one was.
