So I need some help. I went to install a new window motor after having to clean the old one out only to get a couple days of use out of it. When I got in there I seen that the cables we're birdnested in the regulator and there was no way to open it up. I landed on the idea of drilling out the rivets, rewrapping the cables around the pulley, then using some small bolts I have to hold the regulator pulley housing together. I am having a hard time getting the cables wrapped right. It's either I have too much slack or the cables are too tight to fit the plastic pieces on the end of the cables into their spots. Is there a trick to this? I have tried it with the tracks in the up position, down position, middle position. Anybody have some tips to get this back together? Thanks in advance

It's probably going to require a new regulator but I HAVE sucessfully rewound the spindle before, it requires the glass to be off the regulator.
