Stretch Tank Fitment

Take a measurement from the back of the lower spring seats to the tank face.
Both sides measure about 9". The tank is angled back away from axle at those points. If I measure from the center of the spring seat its more than 11".
 
Thank you for those pics . They may prove very helpful for some of us .
 
Could you get another pic from this angle when you have the time ?
