71 HEMI Cuda Convertible 4 speed

IIRC the ET became the Judge and was supposed to be a basic muscle car, so much for that!

IIRC the ET became the Judge...

Correct! On the show hosted by Chip Foose I mentioned before, during an interview with Jim Wangers (aka the godfather of the GTO), he said they went to John Delorean with the ET name, and he replied (paraphrasing) that's a dumb name, and mentioned a TV show (Laugh-in) where a guy was always saying, "here comes the judge" so that's the genesis of the name "The Judge" and the rest is history.

Wangers also said the official name of the car is "The Judge" not Judge, so I guess it's a GTO The Judge, even though no one calls it that. On the other trivia question, according to Wangers, the '69 GTO (The) Judge was the first muscle car with an aero spoiler, but it really had no effect except at very high speeds.

On the Superbird vinyl tops, that was also discussed on this same show (different episode) and the story goes, the President of Plymouth went to Richard Petty, asking what it would take to get him back in a Plymouth. He replied, "a Plymouth wing car."

That was enough to motivate Plymouth to build it, but in order to make the fast-approaching 1970 NASCAR season, and the new NASCAR homologation standard (they had to build 1920 cars for dealer sale, as opposed to 500 the previous year), the Plymouth Superbird wing car was a rush job, based on the Road Runner. As part of the rush, there was a cut seam in the roof and it was just quicker to cover it in vinyl to hide it.
 
Hey SR, I believe the 69' Hurst/Olds had a rear wing that actually created down force, so that may be the answer. No "Googling" here, LOL!

You are correct Sir.It was a rush job to compete in NASCAR.One would think that they would have had in house communication or spying.
 
I really enjoyed the Grand National talk earlier so I thought I'd float this little factoid out there. On atleast the 86-87' turbo Regals (GN's, T-types, turbo T's and Limiteds) there's a light along with the "idiot lights" built in there that says POWER INJECTION. Apparently Buick was considering water spraying either into the intake or maybe the intercooler. Many moons ago I went for a ride in an 86' T-type that the owner had this light hooked up once the car hit 5 psi, very cool to see that. Btw this was an 11 second street car when they really didn't exsist, I still remember that to this day, the car flew!!! He used the windshield washer bottle to make this work, very cool.

Love this thread...

Did you guys know Olds offered an aluminum reared for the 442, a 12 bolt and IIRC it had 10 bolt internals???

It was late 60`s till 72.GM stopped production of the 12 bolt on full sized cars by 72.Not trucks. Buick, Oldsmobile, Pontiac, known as B.O.P. It was special order mostly on high HP models.Do you know the ring gear size on 57-64 Pontiac`s and what splines?While we`re on the subject what year did GM offer a posi from the factory as well as a 4-speed? You may find it on the inner-web but can`t trust everything you find there. Good luck. Feed back please

I'm playing fair here, I have no idea about the answer to this question!
 
I'm pretty sure we used to run a HD Olds "towing-package" rear end out of a '59 Safari station wagon under my '55 Chevy gasser.
If I'm not mistaken it had the 10 bolt cover...with 12 bolt internals. Not sure about the 8.75" ring gear though. Possibly a 9.3"? Either 29/31 splines?
With "Pontiac's" limited-slip?

:dunno: ...Gettin' Old!! (Pardon the pun)

FUN times!!

59-O P was the first year that the posi was offered but was available in late 58.The 9.3 had a center chunk so it had no cover and 31 spline axles.59-64 is considered one of or the strongest rear end to come out of Detroit.The gasser guys love them for the period correct look.GM sold the design to Ford and that was the birth of the 9 in. rear.Hard to tell the difference except for pinion offset.GM had always maintained a 3/4 to 1 in. offset where Ford went as high as 2 3/4 in.
Now on to the Chevy question what year was the posi and 4 speed offered from the factory and which cars?
