window slot bowed, too wide, any fixes?

[Enygma]

hello folks

so i have a 70 stepper that i have a love/hate relationship with. the drivers door appears to have been tweaked out when po was messing with vent windows maybe? the belt line window trim doesnt hold window from both sides and will allow moisture down into door! i know the little brackets below the vent have broken loose from each other, and i can fix that but i dont think that will pull the outer door in enough. any ideas on how to pull the inner and outer door together to close that up?

i searched for a while but dont know what to reference this problem to...

thanks in advance, this place has helped so many times, im sure someone has figured this out!
