Crumplezone vs. non crumplezone hoods

[DetMatt1]

I had a member pm me with a question regaurding the difference between the early `70 Challenger non crumplezone hood and the rest of the Challenger hoods with the crumplezone. I only have a couple of early `70 non cz hoods here so I am posting a pic or two them, could somebody post up a pic of the underside of there hood with the cz so they can be compared by all?

hay matt thanx for posting this..anyone have one with them??or atleast where there suppose to be at?? from what i see my hood is the same as yours..but i might be missing something..old eyes you know lol...thanks again lee

Since there are no replies here yet I will say that there would be some linear indentations in the understructure aft of the rubber seal that would make the hood fold at that point in an accident rather then sending the rear of the hood through the windshield. Somebody should be along anytime now with some pics considering probably 90% of Challenger hoods have the crumplezones.

The crumple zones are on either side of the main beam twards the front of the hood...just forward of the scoops.

hay thanx guys!!now i see...whats really funny is i picking that hood up tomorrow from swept 57, how cool is that lol..now b4 u guys get ur bloomers in a bunch.yes i know my challenger is a early purple big block car...so the flat hood should stay...but i hate that hood lol, so it will be kept and painted at the same time as this new hood. besides i dont have orig 383,(but i think the one i have is real close to build date) but once again thanks to all Lee

well ok, new update just looked, and either my hood is not orig,or my car isnt a early build car, just went and looked,my hood has cz( now that i know where to look) was thinking being vin #1113XX it would be a early car,,,owell...thanx again lee

You can look at your fender tag to see what the cars SPD was. That will give you a ballpark idea of when the car was built. There are more knowledgeable people then I, who know when the crumple zones started to appear. Do some research and you should be able to find out if your car should have them or not.

It looks like that hood is off of a 73. The safety hook is different then a 1970 and the color looks like A5...a 73 only color. I don't know what you'll have to do to get the 70 style safety hook to fit.

hay thanx...problem with fender tag,is the bone head that looked at car b4 me took tag off and now he says he lost it..i even offered him a hundred dollars for it,, still no go. man now im starting to worrie about the hood latch sit....any one know if this will fit???moneys short,cant afford to waste it..ended up buying 2 sets of 4 speed pedals for my demon that way.. anyone know for sure???

hay thanks,,got really worried just then..called amd and they said only diff is size of bolts on hinges ..after looking at detmat's early hood seems only dif besides cz is there's no mounting spot for later latch towards front. then i looked at my car...darn latch is mia anyway so im guessing ill need the later latch anyway....please if anyone knows this swap wont work,let me know...i dont have money to waste.this is how i ended up with 2 4 speed pedals sets for the demon...thanks again lee

your hood is not original IMO , my car was built Sept 2 & is a 112xxx serial #
what swap are you trying to do , just install the Ralley hood ?
if so no problem , the 70 saftey latch is mounted back on the frame under the hood , the later years had the steel pull handle to clear the grille

hay thanx,,went and picked the hood up today..fits fine....want the later release anyway...to old to reach up under there lol wow sept 12 with a 12xxx num....there goese my thinking she was early...thanx lee

 

[DetMatt1]

[Chryco Psycho]

You car is very early , you have a 111xxx serial # so your was built maybe a week before mine in Aug

 

[truckerlee]
