Hurst shifter pic?

Just hooked up my shifter today, will shift 1-2 and 3-4 but can't get the lever far enough to the left to move forward and engage reverse, just wants to select 1-2.
It's got fresh grease in it so looks like it's been apart. (Bought the car in pieces).
Is it possible the part that the lever slots into has been assmembled 180 degrees off?
If any body has there out or the boot removed appreciate a picture of the top of the shifter.
Iv'e searched the net and no decent pics available also my shop manual has no info.
Thanks.
