97 Ram SST, double wall roof?

I was thinking about putting a "Big Sky Racks Overhead Gun Rack" in my SST for my hunting rifle and shotgun, but on the one I am looking at says you need to make sure your truck has a double wall roof before attempting installation. Any body know if it has a roof like that?

Here is a link to the product page:

you can pull your headliner down or check with the manufacturer they might now if you need the optional through the roof mounting kit. From what I get from the description is if it isn`t a double wall you`ll run the screws right through the roof

Like said before just pull down the headliner it doesnt take long.Ihave done paintless dent removal for years and am 98 pecent sure yours is doubled walled because they suck taking the dents out alot of holes to drill.
