Since you already rolled it I wouldnt bother with th extra weight and cost of an exo. Id just go internal so your protected if it happens again. 
bummer to hear you rolled it though...espicially after the tall talk...
im goin with the 4x inovation interior cage or just fab a copy of it
yep time to get rid of those 6" springs n get 4" i was younger when i pickd out the lift, you know "bigger the better" nope i was completely wrong.
Sorry to hear about the roll. Lower it then cut the top off and cage it, that is what I did with mine after ending up on my roof on a hill climb. 4xInnovations cage kit came out pretty nice, although I tied it into the factory cage since I will be changing the rear of the 4 runner around in a few months and will redo the back section of the cage.
im doing exactly what you did hahah i had he same cage in mind and everything, i still wanna keep the cab and bend it back into shape to put a windshield in so i cud still drive it round town
