I'm old and this frame I installed yesterday suits my 2 door...Still waiting for my 2 door Bronco. I bought a 2 door Wrangler shortly after ordering a Bronco and have been driving it for over a year now. It's even smaller than the 2 door Bronco and I find it's plenty big enough for 2 people with the rear seat removed. Even my skis fit in the back at the right angle. Construction isn't one of my hobbies so I never need to carry 4x8 sheets of anything.
If you need to have 4 people in the vehicle forget about having room for any gear though.
