Could someone please post a photo of a door window channel for a model A ? I have two channels but they aren't out of a model A so I am hoping to modify the ones I have to fit in my 'A'. I am not sure if the support portion welded to the channel is center on the channel or slightly off to one side. I will just move the support portion on the ones I have to where they should be for a model 'A'. Knowing the length of the channels would also be very helpful. Thank you.
