OK, serious answer time...
custom cut windshield, rear window, door glass and trim window
redesign of structural reinforcing of the a, b, and c pillars
either glassed or custom molded a/b/c pillar interior pieces
the time to do the body work as well as the basic body work materials (filler, primer, paint, clear)
You also have to cut your roof into 4 baisically and weld it all back together. When you chop the top you are actually making everything smaller. But you have to make the roof bigger. Someone here did it but I don't know his name. Came out nice.
from what i undersatnd u need to go get another roof from a junk yard...then u chop out how ever many inches u want...then u cut the hood in a plus patter ( + )...fill in the gaps and weld it all up and get new glass

just a quick question and my ideas.
to what david said why do you need to maek the roof larger?
i was just thinking about it after looking at customised hod rods my bro is looking it to making. Now i wasn't sure on what i had to all do so i posted.
i was just thinking i would haev to basicly take the a,b, and c pillors completly off... make new ones at the desiered height i wanted and make sure the angles will all line up right with the roof at that height. then weld the roof top back on. i was thinking about getting racing seats and sence they sit so high up or hiegher then stock (from what ive herd) that i would chop it to about 2 inches or about 3-4 inches about the seat.
tell me what you guys think if this would work or not.
Think of the car from the bottom of the windows up as a cone.
The base of the cone is larger than the point, obviously.
Starting at the point, each horizontal cross-section closer to the base is "X" amount larger than the piece before it.
Also, in theory, you could keep the roof the same size, but that will require re-angling all the pillars to match. It would be easier to "platterize" the stock roof....
Here's a visual example, borrowing from ancient history.
Think of your roof at the top of the pyramid, and each step down is 1" of chop, notice how to maintain the same angles, the steps get progressively smaller (or larger depending on if you start at the bottom or top)? The concept for chopped tops is the same.
ok so how would i go about making the roof larger? i dont have acess to a metal roller. if i would be abel to make it out of fiberglass i could do that im pritty good with fiberglass.
i was just kind of messing around on the limited amount of photoshop i have. It looks pritty tight just having the same size roof and have it lowerd. but i guess if its the wrong way to do it then i will have to make the roof larger some how.
You would cut at the red lines and fill in the gaps with a spare roof you get from a j-yard...
IDK who's car this is, but it was the first one I ran across that had a decent overhead shot...
couldn't find cannon's sig, otherwise I'd use that.
ok that doesn't look to hard i might be wrong.
so to make it liek the steps on the pyramid... if i chop an inch off the pillars i need to add an inch to the thickness of the red X basicly?
Well, it won't be exactly an inch... it'll be more surface area. you'll have to take a starting measurement of your roof area, and once the pillars are chopped, take another measurement of the area where the new roof will go... the difference will be the amount of material you will have to add.
