Swapping out a 2.5 liter from a 1988 S-15 Truck to an 305 cid with automatic transmission. Need help in the area of suspension pertaining to front coil springs to use. I understand the springs for a 4.3 V6 would work but should I use springs with a stiffer rate. What sway bar should be used? What would be the best rear end to use? Plan on keeping stock height not lowering vehicle.
