Top Door Channel Size and Installation Questions

[1966BroncoNewbie]

The new channels I ordered from Wild Horses for my 1966 Bronco are an about a 1/2 inch too long. To match the prior channels, we cut off a 1/2 inch of the channel where it meets the upper part of the vent window. track leaving the two metal 'prongs.' We installed the modified channels but one of the 'prongs' has to sit outside the window frame to allow the window to close. It does not look good plus the channels aren't staying in the track. Has anyone else had problems with the new channels being too long? What parts place has the best new channels? And what's the best way to get the new channels to stay in place? Thanks

Picture would help better explain your issue. I used WH channels with no issue. Several vendors but likely all have same sourced parts.
