I recently purchased a 95 Ranger 4.0L 4x4 extended cab. I checked the alignment after I noticed some severe wear on the insides of the front tires and found camber to be out on both sides. I was going to adjust it, but it was already adjusted as far as it can go. I think the problem is old, sagging coil springs (it has over 200,000 miles on it). I want to replace them with factory springs so I checked the spring code, but my concern is, there are 3 digits in the code (BM X). I'm not sure which coil springs to get, or if I should get either since I MIGHT one day swap an Explorer 5.0L engine in it. I'd appreciate any advice.
