Any idea how much weight is saved by going to FG hood, trunk and bumpers?
Of course I forgot to weigh my hood and trunk before I put them back on the car. Thanks, david |

A lot.
If you get the hood that doesn't have the front corners cut out for the headlights, you can cut/remove all the headlight pieces. (motors, lights, the sheetmetal box, wiring, etc etc). So you're able to save weight on the hood and on the headlight stuff. A stock front hood with hardware (hinges, latch) is 35-40 and a f/g is around 10-12. Rear trunk stock is 30-35 with hardware. F/g is 10-12. The f/g bumpers weight somewhere around 5-8 pounds and I'd say the early stock front one are 25-30 pounds and the rear 15-20. This is just what I remember not actual weight. Someone here may have actuals. I'm changed both my front and rear hoods so weightng them now wouldn't give you the the true weight verses stock. Paul |

that sound promising,
Adds up to about 75 - 80 pounds savings not counting headlights. I guess we could get the car down to 1800 pounds and keep the classic look of the car. thanks, david |

There is a little gain when going to f/g rocker panels too. And take those silly front fender lights off.
If it is not being used to go or stop, take it off. Paul |

I dont have much to add here besides: focus on getting weight off the car that is up high (like the lids/top/glass). Roger Sheridan sells a fiberglass skin of our tops that looks identical. Weighs at least 20lbs less. Replace the back glass with a good piece of lexan.

I'm actually gonna do the lexan windows (rear and doors) and "skin" targa top before f/g lids. The weight sits up high and these mods are more "cost-effective" (no prep/paint).
The f/g bumpers save a ton if you ditch the rubber tits and the foglights etc. I eliminated my foglights but kept the horns as I still drive on the street about twice a month. I am going to go to lighter/stronger seats too. I have a single old Koenig in the car now, which weighs a TON. I could probably get 2 fg or kevlar seats that weigh less than this 1. THEN I might do the lids and a Sheridan 6" lip spoiler...next year. |

Oh yeah, I have the bumper weights (stock 73 vs f/g) in my garage...somewhere. I'll try to find that.

All my glass is lexan now. I cut and fitted everything accept the windshield which is formed polycarbonate from "shields".
The windshield is 1/4" which is many times stronger than the glass but about 1/2 the weight. It is also coated to prevent scratching but we will see how that goes. I am babying it for now. They say not to worry about it, use your wipers etc. but for now I am being pretty careful. Also it fit very well. We were even able to use the chrome trim which I wanted for the vintage class. Installed with nutplates for easy removal. Still need to add some tabs though. regards, david Attached thumbnail(s) |

Nice job on the rear window!
Where did you get the windshield? Any idea on what you saved weight wise? |

The windshield comes from http://www.racingshields.com/
We are at 1900 pounds now with full 8pt cage, steel body and bumpers. I guess the lexan saved us around 40 pounds. Gutting the drivers' door saved alot also, maybe another 25. david Attached image(s) |

chris,
the racecar ranch as we call it is larry jordano's shop/home in stuart florida. He has a giant shed where he does all the fabrication. He is really a BMW racer but I convinced him to do the prep on my car. He did a great job. He drove the car at sebring last weekend and was really taken with the handling and low weight compared to his cars. Maybe we made a convert. I pretty much new what I wanted with the cage. Nascar bars, petty bar, rear supports from main hoop to back of car, dash bar hidden up under dash instead of down near your knees, etc. I will post some pics of the build at www.synthesisdv.com/vg later this weekend. regards, david Attached image(s) |

(IMG:style_emoticons/default/laugh.gif) A paint job is being planned. If I could just find a easy to use photo editing program so I could put some of my ideas on a pic and print it I'd be real close to losing the L.A.P.D. look. |

Andy... honestly, er, the "multicolor" look would probably cause me to lose sleep before too long. Remember I'm a "reformed concours weenie" turned race junkie (LOL).
The main issue is cost - I want to do all the fg or carbon body stuff at the same time, if feasible, and therefore deal with the prep & paint work all at once too. We're talking 2 lids, rear spoiler, and possibly fenders and doors too (if I go bonkers with the "R" concept). I still have quite a few other projects to tackle that are higher on the priority list, so I can put the f/g bodywork off. Oh yeah...not to mention that "the boss" wants to do about 1000SF of hardwood floors on the house. (IMG:style_emoticons/default/icon8.gif) (Think $9/SF or so, from what I know thus far.) We need to do it, to get rid of the carpet (Logan has allergies), but it will put a MAJOR dent in the ol' recreational budget. |

just removed front bumper (1973). Weighed 21 pounds with the rubber bumperettes attached. Now they are removed of course. Now what to do with those four big holes? (until I get the FG part) May put the vintage cibie rallye lights there for now.

I used chrome carriage bolts to fill the holes. Like this: Attached image(s) |

My guess was 25-30 pounds for the front.
Of course I included the driving lites and hardware too. So I was close. (IMG:style_emoticons/default/smile.gif) Paul |

My notes (which I can't find) showed 35 lbs for the front including the lights and grilles.
Whatever it is, the f/g bumper is like 5lbs so the savings is significant. |
