[DeTomaso] Window door channels replacement

[Robert Stroj]

Hi, I am about to replace all the door window channels and whiskers as my
channels are completely deteriorated.
I found good tutorials on "pantera-place" for replacing the whiskers, but
could not find much on the channel guides.
If there is a link, please if you could share.

How much dis-assembling is it necessary; any chance of installing new
channel guides and whiskers without removing the windows?
If it is necessary to remove the windows, is there online tutorial on the
process?

Thanks a lot, Robert
