Read all the previous posts I could find on the Dynacron sheet metal but still not sure on the GTO hood for fit and correctness.
My 68 has that bend and not sure I can get it out so am contemplating buying a Dynacorn GTO hood to replace it. Getting ready to paint the car soon and this one concern is holding me up. Anyone with experience on: 1) Accuracy to the original (had read in a previous post the lines were not as the original but that was a post ~1yr ago) 2) Quality and thickness of the sheet metal compared to the original. 3) Fit and finish comments would be appreciated too. Thanks, John |

Mine fits fine and looks great. It saved me a lot of money in body work and finish work. I installed a repro molded hood insulation and it fit perfectly. I read that the center crease ends too soon, but I can't really tell that.

if your hood was previously bent, I would never put it on a car to be painted. The new ones are excellent fits, with the necessary mild massaging noted previously. Can't beat it. JMHO. Ron

I've seen photos of repop hoods on 68-69 GTO's, where it was pointed out to me that the top of the crease/peak (dead centerline of front portion of hood) is a bit more sharply angled/peaked than originals.
It is fairly noticeable when someone points it out. I don't know if the current repops look like this, but if so I'm going to be tempted to find a good original hood instead (mine is also bent). Chris

I saw one on a 70 GTO painted gloss black and that car looked great. Hood was perfect to my novice eye. I also have a 70 GTO convertible and my hood is the worst part of my car. It's rusting (just a little) and has the bend from stiff or worn hinges. I'm thinking about replacing it when I paint it.
I have read that these new hoods are made of thinner metal and are not as strong as NOS hoods. I'd hate to bend a new one. Could some of you experienced body guys comment about strengthing a hood. What I have in mind is reinforcing the two ridges under the hood along the sides that are at a 90 degree angle to the surface of the hood. |

I`ve used several of these hoods, after priming you can finish sand those center lines to perfection. No problems with the hoods being a thinner gauge, fit was near perfect, just make sure your hood hinges are in great working order as they would bend a original hood don`t you know! some picts of the last two I used them on, and they were #1 cars

I did forget to say that one thing is wrong, although minor. The holes for the windshield washer nozzles aren't made correct. There should be one square hole and a screw hole, but the repo hoods have two sqaure holes. I had to use a small cage nut to use the factory screw. Not a biggy, but was a pain.

Do the original scoop inserts fit? I've heard that with a repop hood you hafta use repop inserts, but I don't know which hood mfg it may have been.

I had to grind just a little off the edge of the original scoop and mounting slot on the hood, not a problem though, goat dr. is right on the nozzles, that was an easy fix for me. All in all these hoods are a lifesaver and made very well, and are a great alternative

C'mon- exactly how many separate manufacturers would spend the money to tool up such a unique part?
Answer: Exactly ONE. The Dynacorn hood is the ONLY reproduction hood available. Period. As for stiffness, the repro hood actually has an extra piece of sheetmetal welded inside of the inner frame, to reinforce the area that always tends to bend. You can't see it when installed, and can really only notice it if you stick your finger in the stress-inducing rectangualr cutouts and feel for it. I was impressed that they took the time and effort to address this weakness of the originals. |

Any recommendations as far as the best place to buy these hoods? I see them all over ebay. Who has the best deal as far as initial cost and shipping to AZ? Dynacorn does not sell direct to the public do they?
I'm also in the market for one of these hoods since Greyhound lost my NOS 69 hood, but that story is in another post... Thanks, Kevin |

I put one of these on my 68 GTO, good fit except the center peak was a little higher than the bumper, I relieved it with a torch. Hood scoops will require trimming. These are non RAM AIR hoods so support structure requires the trimming the factory did if your car is RAM AIR. The two square holes are correct for the windshield washer jets. One is for locating the other for a steel thread insert (plastic inserts are available). Steel guage is correct. Overall these are a nice reproduction.
Here's a link to my car if your interested http://ultimategto.com/cgi-bin/showc...68/68h_00282_1 |

OK,
Not that it makes all that much difference, but does Goodmark buy these from Dynacorn? Goodmark part # 4332-200-68 Dynacorn part # 1511. Just wondering... Kevin |

Goodmark actually started this project, but had a falling out with the overseas stamping supplier. Dynacorn finished things up, and got the hoods to market.
My bet is that Goodmark has finally patched up their relationship with this supplier. |

this isnt meant to be condescending, but it still amazes me every time i see folks shutting hoods on cars like this.
remember to, push back, push down. youll never buckle a hood again doing it that way. grabbing the forward edge and pulling down will ruin them every time.

GREAT TIP. OUR 69 CONVERTIBEL SAT FOR 19 YEARS. TOOK 3 YEARS TO FINISH. NOT DRIVING FOR 19 YEARS FORGOT HOW TO CLOSE THE HOOD. THEN WAS REMINDED BY THE GUY WHO DID THE WORK HOW NOT TO BEND THE HOOD.
