1950 door windows
 

New here and will be posting a build thread later.
I'm looking for the channel that goes from the window regulator and bolts to the glass lower frame. and also a replacement front window channel for the right front door.
Also has anyone used any of the replacement regulator rollers? which ones are good or better than another?
Also body, window rubber seals? which to stay away from and which are good better best?
Thanks
Mike
