Leveling the rear to offset the weight of a Leer Shell

New member here w/a question. I just picked up a used Tacoma and it has a Leer 100XL which squats the rear. When I remove the top it sits near level w/the front.

What is the best route to give the truck a level appearance. Not really looking at a complete overhaul w/a new lift or anything, just trying to get options on a slight increase in rear height.

Thanks in advance

 

add a single leaf spring to the rear.

Other options are Hellwig helper springs or airbags. Or if the front is lifted, lower it.

 

Thanks, I was looking into the AAL's since so many on this board talk about them. Is the brand linked GTG? What I've got is a 2015 Pro, so its got a small factory lift as it is, but again the cap squats it a little. (Approx 1" in the rear).
