well as the title says I'm looking for a detailed diagram of the door and the internals along with the part numbers. like in a gm manual.

I'm planning on pretty much replacing everything inside the door. but cant find all this information.

 

Don't think part numbers will do you any good - none of that is being made anymore, so there's no new parts available. You can get aftermarket lock actuators & power window motors, but the rods, regulators, window guides, etc. are going to be used JY or ebay parts. Can also look at Thirdgen Ranch and Hawk's as well - but it's all used stuff pretty much anymore. Every once in a blue moon someone on ebay or at Hawks or Thirdgen Ranch has a "new" part, that was snagged off an old dealer shelf that never sold in the day, but none of those places use OEM GM part numbers - you just tell them what you want.
