Hi Moss, sorry about your luck. The front struts/springs on an F-150 are easy to replace. Took me a day to do a leveling kit, had to pop off the struts and find a strong enough spring compressor, but it's really straight forward if you want to save the labor. When I owned my 2010 F-150, I bought parts from Tasca since that was the best place locally and on the web that I could find decent parts prices. Re-did my leveling kit and changed from the daystar spacers to Bilstein 5100's (much better improvement, had longer range of articulation and more taught handling). Looks like the coil spring alone is anywhere between 55 and 85 bucks depending on which one you have. Pretty cheap part. So this could be a good time to change out your front struts as well since you'll have it apart anyways to swap the spring.
Only thing is that after you re-assemble everything together, you'll need to get it aligned. But you can get close with a measuring tape and dial it in well enough to drive for a week or so until you can get it into the shop.
