rear cab mount removal

[vardenafil]

i'm having some difficulty replacing the cab mounts on my 4x4 truck. the fronts were easy. i just lifted the front of the cab like 2 inches with a jack and they slid right out. the rears are giving me troubles. there is a 5inch tube with a washer welded on to the end that is inserted into the rubber mount. i cant lift the rear of the cab up high enough to get the clearance needed to clear the tube. i can can the cab up a few inches before things start to bind. do i have to take the front fenders off so i can lift the cab higher? or use a sawsall and just cut the tube down so i can lift the cab minimally? im sure im over thinking this. what is the best way to get the rear cab mounts off?
