Hey Paul!

You can use two Thule Hullavator Pro Kayak Roof Rack and Lift Assist w/ Tie-Downs # TH898 with the Rola Haul-Your-Might T3 Truck Bed Ladder Rack you got from us without needing to use any adapters, but you will need to space the towers on the Hullavators between 24-28-1/2" apart from each other. The mounting hardware is all included in the Hullavator when you purchase it new, but if you have an aftermarket Hullavator in need of replacement hardware, I've got the instruction manual linked below where you can find the individual parts that you're looking for. Thule does not have a kit with all of the hardware so you will need to compile all of the parts individually, which I know isn't ideal, but I have linked everything that comes in the kit below, which I've confirmed directly with Thule for a secure and snug fit on your Rola truck bed ladder rack.

Thank you for your response Jerry. I may not need all of the hardware you list, but not 100% sure. I purchased the Hullavators used, and they are mounted to the square Thule cross bars. I will need to dismount the Hullavators from the Thule crossbars and mont them on my Rola Truck Ladder Rack. Do you know if I need to buy all of the hardware you list if I am removing them from the Thule square cross bars to mount in the T-slots of the Rola Ladder Rack? Thanks Paul M

@Paul All of the hardware may not be necessary, and you can re-use hardware from your current setup. Just make sure everything's in good condition to keep your Hullavators in working order.
