Stock Rear Spring comparison XE, SE w/B. Tow, SE w/o B. Tow

[Oldfordowner]

Can anyone tell me if there is any difference in the stock rear springs between the XE, SE w/o Big Tow, or SE w/Big Tow. Does the Big Tow Package use a different rear spring part # to increase Tongue Weight capacity. Would like to know.
