Ok so I’m building a true 4 door ZR2 . If all goes well my frames being donors will both be 2001. Blazer ZR2 is 01 and I’m going to try to save the back half of Florida frame after I build my jig for frame to be secured. I know maybe I’m going over board on a jig but I want it to go down the road straight and handle good.

My question is did GM do any staggering of the front wheels in anyway? I will be measuring center line of axles front to rear as my final check before fully welding frame. I ask cause I used to work with race cars and that’s kinda standard there but I do know a few auto manufacturers did this as well on occasion.

Thank you all for your help. My build is under 98 4 door ZR2 build. That’s the year frame I have that I know is good and the original vehicle that started this project.
