AutoCAD Jeep Drawings

[bluebullet6]

Does anyone have access to detailed AutoCAD schematics for the main exterior components of a Jeep XJ? I'd be looking for a side, front, back, and possibly bottom dimensioned view of the xj. I'm hoping to make some custom bumpers... but as I'll probably botch them I'd like to draw it out as much as possible, and also be able to play with different designs and such.

I have LT 2007 on my computer, and access to 2007 Professional.
