2nd gen. Making a Lil progress

So After sitting on the side of my house the past 7 years, totally forgotten on the back burner, I finally pulled the 89 out and started getting it road worthy again. Got it running, Still got to get rid of knock off carb and get a real one..... but in the mean time it got full 2.5"F- 4"R beltech lowering kit. Quotation I have, is what is causing the driver side front to sag? I've put 3 sets of leaf springs under it, 3 says of coil springs under it and still there is a visible dip in the driver front side. The only thing is I haven't got it aligned yet, but unless the torsion bar is way outta wack I don't know what is causing it. Any suggestions or ideas???

check the coil springs - one should be taller than the other - that is the driver side coil. the rear shouldn't matter.
