Rear driver window regulator
                    My rear driver window regulator is sticking.  I have taken it out after replacing the motor, bushing and assemblies.  I can't find a anyone making a replacement.  Is there anyone making one ....if not any suggestions to getting it moving smoothly again?  I have tried a whole bottle of WD40 and no luck.  It gets stuck half way down and has trouble coming back up.

If it turns out you do need a regulator I have a used one. Bought it when I thought my regulator was the issue but ended up not using it. You can have it if it helps your cause.

Next, if that isn't the case, I wonder if the rear window got broken when previously owned (if that is the case) and pieces of glass fell down into the regulator, locking it up. I haven't found many things that PB Blaster wasn't able to unfreeze, if it is rusted up.
