I just replaced driver side regulator, you do have to drill out the 4 rivets that are holding it. You do not have to remove the motor. I used 1/4" bolts to replace the rivets. Be patient and you'll get it ok. Thanks to old bubba for mentioning how to get the old reg. out of the track. Use a glove to reload the spring when you reinstall it, it BITES!!! 2 hour job.. not too bad though. I don't claim to be a mechanic but I did stay at a holiday inn. ;-) |
