Zr2 vs. Non zr2
As I own both a 98 ZR2 and an 02 Jimmy SLS I get to see the differences almost everyday...
From what I have seen the frames ARE the same. But here are the differences I have noticed:
Front cross member sits lower and further back on the ZR2
Different control arms that are mounted lower on the frame then the NON ZR2
The front skid plates are different, but the other 2 are the same
You do not need to remove steering shaft on my ZR2 to get at the #3 plug.
Springs are 2" higher in the rear, but mount in the same spots.
Shackles are same length.
Now before I do my SFA in the spring, ill actually put both trucks on jack stand side by side. I then will get my buddy who does photography to take pics, and I will measure both frames.

as for the 'locker' look into the G80 "gov lock" it is an eaton 'locker' in title only. it's like a posi rear end.... nothing special really. i believe all g80 axles have the same thing, with the ZR2's being wider. that is why the vehicle has such good low end torque and shifts so firmly into 2nd with a sweet tire chirp if you play it right.
Might be wrong though....

see, i had told Curtis that the frames weren't any different between the two, and iwas hoping that you would take it upon yourself to set us straight.
on the wider SP, where is it wider? and i'm guessing the mounting points are different as well.

no one said the frame was wider old skool 
i said the axel is wider. as for the plate, it is LONGER i believe he said... it was in another post, either way, with out a valance the filter and housing would still have shown 
As for the cost of the boggers and rims, then it looks like i'll make a killing on this trade!! I'll pm you my mailing address...
