The airbag suspension is bad on my Grand Marquis and I want to do the conversion to the passive springs. I'm an intermediate mechanic I can do brakes, calipers, tie rods, ball joints, water pumps, oil pumps,
​​alternators. Will this conversion be difficult for me? Should I be able to do it myself easy enough? How many hours are we talking. If anybody has done this before. I just don't want to get an over my head, or to take me 3 days
