I think I have a new lift clamp in my box of spares if you have need. Bought but not used when I replaced a window winder mechanism. Stirlingmoz
That’s the window up now ready for new clamp Think I got to the bottom of the problem lol thanks to all you replied with tips got there in the end
Thanks Stirlingmoz but I’ve got quite a list of parts so JK will be getting an order tomorrow anyway but appreciate the offer
Mine used to do that - the metal glass holder had come adrift from the mechanism . I used to have to keep balancing it on it until I got a new glass holder from JK and bolted it back on. https://www.justkampers.com/211837571a-window-lift-channel-t2-bay-1967-1979-brazilian-bays.html The old glass had the remains of the old holder firmly glued to it but I managed to jam this into the new holder and bolt it on OK .
