34 Ford 3W door+rear glass channel replacement

[fordson]

I have to replace my door and rear roll down window glass channels on my 34 Ford 3 W coupe.
The rear glass channel for the roll down back window i got from VINTIQUE, bad shape and fold, not bevelled at all, horrible.
The channel itself also seems to be much shorter in lenght with regards to my original rotten one. Dont know if any correct length replacement is available. Does the length of the rear glass channel have any effect on the window movement or stability!?
Has anyone any experience with reproduction glass channels?
Any recommendations what replacement channel to get for the rear roll down window?
The door glass channel by United Pacific are much better quality, the fold of the runner is the correct shape and angle.
It seems to me those are good replacements and will work properly!

J-Pegs:
Rear window: Black glass channel VINTIQUE / Grey glass channel my original. Note the difference in fold and length by comparison.
Doors: Black is United Pacific in comparison to the original. Correct fold for the runner

Anyone with experience having replaced their door glass channels with United Pacific ones?
Thank you
