Bagging questions

I am in the process of getting ready to bag my truck.
I only have enough money to bag one end of it right now.
Trying to figure out which end is gonna be cheaper.
I only want to have to do it once so If I do the front I am doing tubular arms.
What all needs to be cut out of the front to lay out?
Does anyone have any pics of what is to be cut out?
And any pics of where to relocate suff on the engine bay?
I am running 235/35/19
Does the firewall need to be tubbed?
Do I need to Z the frame?
All this concerns me
Makes me want to bag the back first cause it will proabably be alot easier.
Thanks again

Pics of my yota front bag install on my site.. check it out in my sig. Hit me up on aim if you have any questions

What do I need to do to remove the charcoal canister?
Will I have a check engine light?
or any other problems?
Thanks again

Relocate the canister if you have smog checks. Put mine in the rear outside the frame rails beween the front bed supports.
