I'm going to be using Chevy DRW D60 front and 14bolt srw rear from a van. You really need the width for the wider spring mounts on the M and tire and brake clearance. I'll be running H1'. Planning on a 6bt or a 24 valve with p pump. Nv4500 and an np205. I also have a gear vendors overdrive for a 205 for double overdrive or gear splitting. I want to be able to use 4:88 gears for stump pulling torque and still go 70 with the diesel on the double or single overdrive.
