OzyDuster74 chassis connector questions!!

So have a wheel tub question, when you tub using the traditional kits it doesnt address the isssue of the outer part of the tub. As simply stretching an inch to the inner of car.
A lot of cars tubs go straight up but the A body tub darts in meaning if wheel runs close to lip of gaurd it will rub unless jacked up in the back. How are people getting around this?
See in this picthe tub goes in an inch from the quarters quite quickly.

My friend had his diff all folded etc and when fitting found that with the ten inch wheels and 315 tires to sit in the tub had to be back spaced as seen in the pics and doesn't look right.
