fitting one piece windows

hi all,

just after some advise when fitting one piece windows do i need to take out the steel channel section at the front of the door so the baily channel can be glued into place or would it be recommended to leave this bit in?

any help muchly appreciated

regards,
scott

i have cut the bottom dog jeg off the base of this bit, bit of a bugger i need to do some painting where the rubber were left in there when car was painted 🥲

one piece windows are a bit nasty to fit 🥲
