Did you contact Todd at DRB as per my earlier post?
These 2 Coupes below are 2 of the apparent 5 DRB had bodies for. Both reside in QLD. The DRB guys could confirm that front suspension but looking at these 2 versus your body Im not convinced its a DRB.
I suggest again calling Peter or Todd Ransom as they may be able to shed much more light on this subject than most.
