Re: GM Stocker rear end
 
Yes! Danny Gracia Right in front of a drunkish Tom Compton. I was told that the "manufacturer" has final say so over the use of their product. If GM says no NHRA says NO! There were a couple of other tech and officials there too, this was last year. I think I made a little too much noise and logical sense to them. but since I was not wanting to upgrade to a 100k car my opinion mattered NOT!

A prime example would be a red Olds stocker that recently moved from the west coast to the east coast. It has been through tech many times and always passes. I believe it just won a divisional as well. But it clearly has a narrowed rear axle and altered frame rails. There is no other G body car that sits as low to the ground and has the tire clearance this car does. How is that possible??

A simple check of the distance between the backing plates and between the wheel wells may shed some light on this. But NHRA NEVER checks these things. They must not own a tape measure.

I doubt they even care about bogus stuff like that. Otherwise they wouldn't allow even half the junk they do. So I say, stick the nine inch Ford in. IF they catch it, as for forgiveness.

A copy and paste of the rulebook means exactly what it reads. If a housing is narrower than specified it is clearly illegal for use...period.

Huge debate on the floor at SEMA Went rounds explaining and arguing my case and was finally told"You want to use the new rear end? Buy a new car and get rid of your old one!"

GM officials have no say in the matter They submitted the new car to NHRA and NHRA allowed it in Stock which means they abide by the same rules as any other vehicle...I have never seen any separate rules governing COPO cars, have you? A flat refusal to allow the new housing would require NHRA to re-write the rulebook and put them on very shakey ground in their argument. Do you believe a swap of their current housing to a 12-bolt in the new car would be illegal?

Not letting this one slide. COPO and Dragpak yes. But tell me what is nowhere near stock configuration about a CJ rear suspension, and what they are allowed to use that older cars are not?

Re: GM Stocker rear end
 
The rule doesn't save the racers money; 12 bolt, Dana, and 9" cost similar money to build right. Nor does it make the car more "authentic" or "stock" since we see a lot of cars that only had 10 bolts, or 8.75", etc. running the bigger differentials. If it is OK to look under the hood and see a non-authentic aluminum water pump, that is a lot more obvious than a non authentic differential housing.

Oh, sorry, I was interjecting logic and that has little to do with the issue.

If we can get tech involved here may help the case !!

Rule book states - "Distance between backing plates may not be changed."...

Another "Stock Eliminator" rule that is totally ignored anymore...

there are lots of "bogus" examples out there if you just pay attention.

Re: GM Stocker rear end
 
i was told the copo is a part # (no vin)there is no where that you can look up a part # for a gm copo rear end:confused:, thats what alows them to say older cars can't use them because its not a over the counter part sold by gm unless you bought a copo or a rolling chassis:mad:. i don't think you can even buy a 2012 camro and build a stocker with that rear end because it didn't come in any corperate car:eek:

Re: GM Stocker rear end
 
The COPO should have to use a 10 or a 12 bolt, the Dragpack cars a Dana 60 or an 83/4 Chrysler and the CobraJets a 9 inch or an 8.8 Ford unit. I am limited to a 10 or a 12 bolt, it should be the same for everyone. My point is the factory cars get to use all of the new technology components and the rest of us are stuck struggling with old technologies.
