I am going to remove my roof rails that i think are from a blazer but anyway i am getting rid of it. So the info i need is...

What brand of roof rack can i buy that will mount to the gutterless roof that also has spare tire mount and light mounts.
Or do i have to buy thule crossbars and then a bajarack mule basket from trdparts4u.com

I have googled and all i get are full length baskets rather than half size baskets(i only want a backet to cover the back half of the roof). Any help would be great. i need the info cause i am putting together a price for redoing all of my exterior.
