Is that photo taken in Seaside?

Scott S 06-03-2013 11:03 AM

Has anyone ever backdated further - i.e. instead of making an SC/Carrera into an RS, making it into a true narrow bodied car - like an R or an S?

Craig T 06-03-2013 05:32 PM

Hers's mine. From a 75 to a hot rod. ...Not trying to be anything specific, just a tribute to the old style.

Great thread! Love the backdated cars. I've been looking for my first 911 and really wanting a long hood hot rod.

Am I correct in thinking that any backdate to create the "longhood" look requires cutting off and replacing the front bulkhead? I'm talking specfically of backdating a '84-'89 Carrera or a 964. No way around this...correct?

no, you are not correct. For the front, it's entirely bodywork. There are hoods offered that would allow for a 100% reversible backdate. For the front, at least.

Getty Design now sells a "longhood conversion" that has a latch mounting further up the hood to allow it to fit a 74 911S-964 without cutting off the nose. They also have fiberglass early bumpers that bolt on. I've seen one done, and it doesn't look bad until you open the hood. It's also quite a reach under to get to the latch.

-------------------------------------------------------

Getty 74'-93' Long Conversion Hood

$569.00 - Core Mat
$709.00 - Foam Core
$959.00 - Carbon Fiber

Fits 911 - 1974 thru 1993. This is a special long hood with short hood liner. For converting 74' or later chassis to a 73' Carrera RS look without having to change the front tub panel.

-------------------------------------------------------

I really like Getty products, and this will save a lot of $$$ at the body shop, but after looking at and comparing it to one done right, I decided it was worth the $$$ to go all the way.

I doubt Magnus could catch Craig. SERIOUSLY doubt it...

88911coupe 06-04-2013 09:16 AM

Well that's great news...it seems like every thread I read on creating longhoods used substantial fabrication work up front. Good to know that's not required.

Scooter 06-04-2013 09:25 AM

I would not say that substantial fabrication work is not required.

Be aware that if you use the fiberglass long hood with the later latch position, you will be chasing the usual fiberglass distortion issues on a very low-crown surface. You will have to forego hood shocks. You will have to cope with the fiberglass "settling" over time.

Having done a backdate once with a fiberglass long hood, I would not do it again. Fiberglass and low crown panels are not a good combination. Disclaimer: I've not tried a carbon fiber version, and that could be a lot better -- if it's 'real' carbon fiber.

Other changes to the chassis to do the backdate are quite minor. You can do them yourself in a weekend.

Even a "real" carbon fiber hood has the same issue. I used a real CF hood with extra reinforcement to avoid hood pins. It's much stronger than a typical fiberglass one, but not that light. Plus, only a few months past the painting it already shows the weave across the surface.

I fully plan to have Esposito paint and install a steel hood in the upcoming winter.

1975 Euro 911S is now a 2.8 twin plugged carbed homage to the 1969 TdF winning R of Guy Larrousse and Laurent Gelin.
10 years of effort but worth it I think.

I'm wondering why so many people take the time/money to do a beautiful complete backdate but than use the wrong mirrors and wheels. It makes a very realistic looking long hood look like, well a backdate. IMO.:confused:

haasad 06-04-2013 12:59 PM

from my position...

Couldn't afford those 7 inch by 15 fuchs for the back, don't like silver and black.

Like Durrants but not the fact I can't see behind so made a new mount.

You might also notice the "wrong" pedal box, cage, headlamp covers, door handles, airfilters , dizzy, arch flares, wheelbase... etc etc .....;);)

They are "correct" NSU front lamps though....they were cheap:D:D

Real CF with polyester resin, or Epoxy?

I suspect FG or CF makes no difference if polyester is being used. It's the polyester that is shrinking causing issues.
