Need frame specs for 01 Silverado 2500 4X4 frame
 

Anyone out there have a tech drawing with measurements for this truck? I ripped the right front wheel off and it rolled the rear lower control arm mount in before the ball joints let go. I suspect that it also affected the left side as well, because they're tied together with a crossmember. I would like to get any info on how to measure this thing when I pull it.

I'm sure someone out there has been through this, any tips are appreciated.

A search didn't turn up anything, and I apologise if this has been posted before, if so, please link me to the original.
