Brandon, here's a pic of the pedestal from my CVX. They do tilt back. Are they the same as the ones in a CVZ?
Not a good view of the tape measure.
Anyway it's 4 3/4in. at the center, 4 1/2 in. at the rear and 5 in. at the front
The base is 7 1/2in. wide and 10 in. long.
The top (were the seat mounts) is 6 1/4 in. square.
