anyone know a good way to get A/C from the front of truck to cap?(no backseat air, just front)

 

On my ranger I used a clear inflatable boot from a truck accessory place. You stuck it between the windows, and blew it up. Crank the A/C and the cold air flows right back, especially with a window cracked in the cap.
The inflatable boot was a little noisy sometimes but it worked great to keep it cold/warm back there.
