The problem with using the luggage carrier for the t-tops is....there really ain't no way to strap them on there without damaging the paint...or having them fly off as you run down the road. Not a good feeling....
The '77 racks have provisions(pins) for using the "T-Top carrier brackets", that will fit the tops, AND strap them down safely. You can get a '77 rack easily, but getting the bracket set-up is next to impossible, without having to get a 2nd mortgage the house.
