lookin good. glad to see you got a manual too!
as for the seat belt cutting across your neck you might be able to find aftermarket solutions. they make these lowering brackets you buy that will lower the seat belt
just make sure you buy the best one that money can buy. safety is the most important aspect of the car.
And honestly having it cut across your neck is not a good measure for safety so look into changing or modifying the belt bracket to make it safer.
my girlfriend has this same problem being the same height.
