Went home and did some quick measuring! I built a "T" shaped frame! Looking at the "T" it's 48" tall by 60" wide. Once assembled and laying on top of the Jeep with the bottom of the "T" at the rear wind, there are 2 "L" shaped hooks that slide in between the back of the hard top and the opened rear window that catch the back of the hardtop. On each side I have eye bolts that I run a tie down between to hold the front half of the top up. The hoist is attached to an eye bolt that is 18" off the rear of the hardtop. The side eyebolts are 58.5" inches apart.
