Help 02 ford f150 lightning problem! Need someone with knowledge?

I recently bought a 02 ford lightning thing is the guy lowered it a bit way to much. I want to put it back to stock height but i can't find them anywhere. I went to the ford dealer and they said that the coil springs were discontinued. I was reading online that you can use regular f150 springs. Is this true? And if so which ones? V6 or v8 f150 and does the cab size matter?

Do you know HOW the vehicle was lowered? Some dummies will cut the coil springs, but that is not very common anymore; usually lowering blocks are used… And as for the springs - the f150 is the same as the lightning, so if you look online, you will find many sources for the springs BUT again - be sure you need them
