Just show them my pic. Tunnel won't sit down, X-member is right under the trans mount. Driveshaft is about a foot long. They'll want you to eliminate the shaft -and it's safety hoop- and connect to the Jag yoke. Like a Cheetah-no driveshaft.
None of this is worth the effort and expense-the GV is about $1800 last I looked-more if you've got to pay to butcher your car. That's a few years worth of gas...
