Thanks for the info guys. Heres what I have so far.

92-94 trooper are about 11-12"

95+ troopers are 12.5-13.5"

1st gen Rodeo (and probably amigo, trooper and P'up) are 10-11"

Now the reason I'm giving a range for all these is because of the differences in alignments.

The basic breakdown as I understand it is this

89ish-95 amigo rodeo P'up and trooper are all the same (10-11"?)

95.5-97 rodeo have a different front end with longer tie rods, still undetermined

92-94 troopers are one length (11-12")

95+ troopers are slightly longer (12.5-13.5")

I think that should cover all the different models and years, unless someone has something to add. The only one here I'm not sure of is the 95.5-97 rodeos. I know RodeoGuy said his is a 95.5 but it seems to fall into the range of the early trucks, and i've heard that the later 1st gen rodeos had longer TRs, closer to the length of the 92-94 troopers.
