32 Tudor door latch/ window channel problem (fouling).

[Mart]

Hello. On my 32 sedan The two channels that support the rear window channels in the front doors were broken. I repaired them and now I have fitted them I have a problem. The door latch fouls the channel when I try and open the doors. One fouls so bad I can't open the door. The part that fouls is the striker and the area that fouls is arrowed in the picture. It must be said the area is very congested and Ford seemed to have struggled with this judging how the channel is cut away to such a degree it is seriously weakened in this area.
Is this a known problem? Does anyone have any helpful tips to get around this?
Any help appreciated. Mart.
