Advice on restoration parts

[orbot]

So i became a victim of aging on my truck, i changes both doors and right hand side fender. now i took apart my doors to get all the stuff on the "new" ones and all the damn weather strips fell apart, they cracked basically, found out my window motors are old and out of shape, also the some rollers on the regulator dont spin anymore.

Wheres is a good part to buy the weatherstrips and can you get thoose rollers for the window regulator.??

Looks like ill be taking the doors apart once again.
