Just got a crew cab 93 d250 crew cab cummins with NO rust at all. im swaping it to 4x4 and nv4500 from 47re And doing an 8 inch lift. So for the 4x4 swap i need everything but the axle and the springs. Are the spring shackles, mounts, front frame truss, and steering components the same on all first gen body style 4x4s? If so it would be alot easier to get the needed parts. Thanks
