Are there any differences between the 2wd and 4wd NBS 1500 trans crossmembers? What about frames aside from the front diff. mounting bracket and steering rack mounts?

 

the crossmember is the same, but the tranny mount itself is different. the front end of the frame is pretty different also, all the suspension pickup points are different. the 4WD has a steering box/idler/pittman arm, the lower control arms are completely different, the upper shock mounts are completely different.

 

The cross member is different 4wd to 2wd.

4wd CM on the left (obviously slightly modified) 2wd CM on the right.

 

Somebody's got a nice floor. Say- do those sprinkles help to keep the floor from getting slippery, ie- do they provide some grip...........
