There are several different options for mounting 1A towers to a shell. The options are;

2) Wide Body Brackets - The Wide Body extends outward more to give added clearance for square-sided shells and may allow mounting the bar lower on the roof. It is typically used with 1A Towers with HighRise Spacers . Dimensions: 5.5" long x 2.25" wide.
3)Top Loader Brackets - Used on top of the shell or camper, can also be used with the 1A Tower or Q-Tower and Q-41 clip. Dimensions: L 7.10” x W 2.50” x H 0.75”
