If I recall, the 94-2001 1/2T and 94-2002 3/4-1T would be the same one. In 2002 the Dodge 1/2T went away from the straight axle and the spacers don't work since they are torsion bar.
The 2003-2006 3/4T - 1T kits are listed together, so everything should be that same for those. The 1500 Mega cab is listed seperately of the 3/4-1T trucks...so that may be a little different. I doubt that it would though, that would mean DC would have to spend a little more.
I guess you would need to know what year 1500 it is for, then you could search it from there.
