yes they will fit. all F250 from 99-current have the same bolt pattern. this isn't the same for duallys though, they changed in late 03 or 04 i believe.
no
Yes they will. As long as it is an f-250 or greater and the a 150. 99-07 are the same pattern. early 99's are different.
No.
If they are both 6 lug they should fit, the toyota wheels are usually not as wide as the chevy wheels
Not without modification
yes
It depends on if they are the same bolt pattern.
My 99 F-250 SD came with LT235/75R16, but it will take up to LT275/75R16 on the stock 16" wheels.
99 + 67 = 166
A 99 7.3 F250 just has a fuel filter on top of the motor.
Assuming that is 67.676767... with the 67 recurring, then: 67.676767... = 67 67/99 = 6700/99
