OK everyone, just found this site
Im currently building a VR commodore panelvan using the turret off a wagon and grafting it to a ute. Hopefully all my dimensions are correct as I am trying hard to replicate the feel of the HZ vans. I have the roof line at 190mm above the standard sedan hieght which is close to the originals. Been doing a fair bit of head scracthing to get it this far. Hope the pics do justice sma.jpg

Ill try and get some more pics up when I get a better connection
