canadian spread

so the truck I just bought which is a international 2674, with a prentice ts33 mounted behind the cab is turning out to be great for my tree service work, the power and reach of the boom is awesome, it is slow but I don't mind to bad. however it has a Canadian spread on the rear and 425 floats on the front which equals a truck that does not turn, it only has a 268ish wheelbase but it takes a 2 point turn to get into most driveways, it just pushes the front tires. can I just swap the walking beams for closer units and move the bump stops?the steering stops are all the way adjusted so the steering arms are already hitting the steering boxes
