Thanks for the replies. I will be doing a lot of measuring in the coming days. I think 46gmcpu is probably right unfortunately. Just from research it seems the track width on the 52 is 61 inches as coilover said. The Tahoe seems to be 65 inches so 4 inches wider.
This is all just preliminary. What she is getting is a running driving truck. So it can be left as is for now until she figures out what she wants to do.
