front bar tube size

[flyinwall]

After hitting a kangaroo the other night i have decided that i need to make myself a solid front bar and i am not sure what size tube to use
i was going to start with a piece of 4"x2" box and go from there but i am unsure what would be the best way to go so can anyone help with designs or suggestions
the vehicle in question is a 99 mitsubishi challenger
and yes i did search but not much came up for me

Don't they have airbags?

[flyinwall]

unfortunatly yes it does

If it has air bags you can't legally mate your own bar but it's up to you weather you do or not

Depends on airbag system used.
