Like when putting the guts of a door back together. It would be nice to have some assembly instructions. From pulling it apart and assembling it several times to work out the fitment of an electric regulator it looks like this is the sequence. This is for electric window regulator. I've no idea if a OEM manual regulator would fit in the same sequence.

1. exterior door handle and lock
2. vent window assembly
3. division bar (but getting it inside the door is a bear)
4. insert window glass but lay it in the bottom against the outer skin
5. lower felts (actually not sure where int he sequence to do this)
6. upper and back window channel
7. slide window into channels and push to top
8. install latch and lock side channel simultaneously.
9. inside door handle and linkage to latch
10. window regulator
11. then somehow seat window into the lift channel (I'm not sure how to do this, with just tape or lay a thick bead of butyl window sealant in the channel and push the window down into it.
