the engine crossmember on the 2wd frame is the massive crossmember- yes you can use the crossmember from ord, or any 4x4 engine crossmember, u just have to have the mounts that bolt to the engine mount and to the crossmember. Thats why im just gonna cut down the 2wd engine crossmember - its cheaper than the ord crossmember and it will provide protection to the engine.
The very front crossmember is diffrent between 2wd and 4x4, i have the one for the 4x4 frame but i just left the 2wd one in there. The 4x4 crossmember has the holes on the bottom for the sway bar bushings- so im just gonna bolt a flat piece or frame rail under the front crossmember to bolt the sway bar up to and it will act as a skidplate to.
