NBS power window question

[99-2door]

OK I have a pair of NBS window regulators and motor assmeblies. I need to find out which is the left side and which is the right. So, does the motor mount towards the front of the door or the back. If somebody doesn't know I will have to remove the door panel on a truck and find out.

Thanks guys,

Jason

The left door has the motor towards the front, or the to the left. Spool is on the bottom of the motor.

 

Im waiting for parts on both windows.

 

GMs' really out done them selves with this design.

 

Everyone will have to do them eventually.
