Plus I will have fixed up my truck to my specs, and I won't want to start again.

I have seen online the drw axles are wider the srw axle, and they use the wms measurement. What does wms mean? I will use rear spacers so I can upgrade the axle I have now to suit my plans, and not have to replace it later. Also I can set the rims right where I want them for the perfect stance.

Also C20, and dually A arms are the same. It is just the spindles where everything gets different? I wouldn't mind rebuilding my front suspension first, and then convert it later.

I am looking to buy a front cross member here in a few months to start my gathering of parts, and rebuild of my front suspension. Plus I really don't want to start buying parts till I figure out which way I want to take my build. Right now I am stuck between off road tires, race suspension truck, and slammed dually for cruising.

WMS can stand for 'wheel mounting surface' & is commonly used when indicating where/how a rear end was measured.

C20 & C30 spindles are the same from what I could see when I was looking for C30 spindles. The difference is the rotors: SRW (single rear wheel) or DRW (dual rear wheel) 8-lug.
