First things first SAFETY,SAFETY,SAFETY......did I also mention SAFETY.
SAFETY
Safety is no accident, when I chopped I was using the angle grinder to cut out the supports in the roof and it kicked and hit me in the face. I now have a scare about 3 inches long that is permanent. ALWAYS use the safety equipment (i.e. glasses, gloves, and guards)
the other part of safety is saving your own arss in case of a roll over. I recomend that you build a cage at the same time.....why don't I have one yet because I am not done with mine yet, and I want an exo.....
PLANNING
I started with months of planning. driving around with no head liner or back panals, marking and measuring. then one day I got out the sawzaw and welder and recruited my Brother-in-law to help and went to town.....
Caution: when cutting the roof off your truck tell your spouse or signifigant other......when my wife got home I made sure my friends were still here so she wouldn't blow up right off. instead I just got the "I'm going to kill you in your sleep you crazy #@#$#%@#$" look.
All joking a side every chop top is going to be a little different, period. the only thing I can tell you is that the majority of people just chop the pillers and acroos the back of the main cab and call it good. in my messed up head I guestimate that it should knock off about 300-500lbs. the rear windows being most of the weight.
When I did my swap I wanted it to be a little different and definately more water tight. I still leak but not on my head. water usualy is in the floor but thats ok I just removed my carpet and deal with it. this also helps to clean the truck when you sink it in a creak and you get 4" of water in there
First step: move all electronics higher. On some BII's there is a computer in the rear panal on the passenger side....what it does I have no idea but you need to move it up so it dosent short. the ECM should also me moved from the kick panel in the front up into the dash. ford computer can see water from a mile away and they will fry. they are very sensative to this so be warned.
second step: remove windows. on some they can be unbolted. others have to be cut. even if you unbolt they still might need some help....be carful, remember what I said about safety.
