I would use a fj60 axle or 80 instead of that old 40 axle for the front. In my opinion if you are going any bigger that 33" tires, the track width should be increased. And a fj60 axle would do that. Also you get the beefier steering knuckles with em. Also, I just did a 2" body lift on mine, its like a 40 was made for such a mod. If done well no one will notice either. FJ40 guys will wheel with me all day and finally notice at the end of the day. And it makes pulling the tranny out wayyyy easier. Maybe it would help you also.
