A few months ago i sectioned my 55 f100 hood, removed 1 1/2 at the front of the hood, its a relatively easy job that can be done in a day. Tools needed: -mig or tig welder -butt weld panel clamps -masking tape -marker -hammer and dolly -grinder and cut off wheels first thing with the hood removed there is an angle iron in the center of the hood which is spot welded to the hood hoop, these spot welds need to be removed, re-install the hood and lign it up to the cowl, make a mark with your marker at the center of the hood and on the cowl, do the same on each side of the hood, these serve as lign up marks which you will use later. tack weld a piece of scrap plate on each side of the hood and tack it to the cowl, this will hold your hood in place, i also ran an angle iron in the bottom center of the hood side to side and tacked into place at the back of the hood you want to measure and mark both sides of the hood equally upwards and put a mark where you want to do your cut. stole my wife`s cloth tape! you want to measure from the end of the hood to 3/4 of the way down the hood (or 41 shown on the tape) mark it and do this on both sides, this is only a reference point to measure up your hood. at this point lign up your tape with your last measurement and mark down 4 , 6, 8 inches, each side of the hood choose the amount you want to remove from the hood and get that width of masking tape, now run your masking tape from the back of the hood to the front using your rear mark and the 6 inch mark in the front, around the front to the other side. grab your grinder and cut off wheel and cut along the bottom of the tape all around the hood remove the top of the hood, disconnect the hood tension rods, cut and remove the rear hood hoop support re-install the top part of the hood, ligning it up with the marks you did on your cowl, lower the front of the hood to your desired height making sure there even on both sides by using your marks (4in & 8 in) drill a hole through both hood skins at the front center and fasten them in place with a screw both parts of the hood slid into each other what i did next is pushed both skins together (6 inch section each side) and marked the top part, took my grinder and cut out that section with my but weld panel clamps i ligned up both skins up, made sure my measurements were good and tacked both skins together both sides keep doing this on both sides until its all tacked up, if both skins do not quite lign up you might have to do some vertical relief cuts as seen in the picture the front is done the same way but material must be removed when doing the vertical cuts in the front rounded sections (pie cut) after hood was completely tacked up into place, you want to keep tacking around and inch at a time leaving the hood cool off so it dosent warp, until the hood is completely welded up.re-install your rear hoop hood support and rods, reweld your rear hood support angle to the hoop, and this is the look you get.. Hope this helps someone else in the future, when i did this there was no info that i can find on how to do this.
