New window regulator showed up today so I had no choice but to get the VX back into top shape (couldn't have it just falling apart)...
Pretty easy exchange. Had to be careful with the three phillips heads that held the motor to the regulator. They're soft metal and mine were extremely tight and hard to break loose. Without the right bit it would have been easy to strip the heads.
Interesting to find that the bottom bolts for the center rail had spacers between the door frame and the rail...who knew????
Pretty easy to get the window adjusted with the SBC bracket AFTER I got it into both the front and rear tracks correctly.
Works great now and this was the second step to the fix that my window required.
