Dually Questions

[74 stepside]

I want to get a crewcab square dually and I have a few questions. Im familiar with 1/2 tons but not duallys. I want one to sit like this red truck. Any one know approx how low this might be and does the bed need to be cut for the rear diff to clear? Would the front tires hit the inner wheel wells? Not looking for a bagged show truck, just a clean static dropped truck that will get driven. Also, anyone have any pics from the 80s of duallys that pulled race cars or drag boats? I remember the big thing was to have sleeper shells and wings. Alot of them had matching paint jobs of the drag cars and boats they pulled. Although the wings arent my thing, would still be cool to see some old style pics.

Looks ike a 6\8 to me, i had to pull my inners when mine was static dropped on a 225 75 16 tire. The rear rarely hit the bed but i never hauled anything.

Here's mine. 3" spindles and 3" springs in the front and a flip in the rear with 5 springs total and helper bags.
225-70-16 on the front and 235-75-16 in the rear. The front tires hit the wheel wells on big dips. The rear never hits the bed but i havent towed anything yet.
I can't get the pictures to load, i will try later.
