Default Truetrac or Eaton Posi - 12 bolt
Hey guys, about to pull the trigger on ordering some kit to upgrade the 12 bolt in my 68 camaro.

Was ready to order a truetrac carrier after reading good things about them. I've also noticed a few threads about noisy truetracs (mainly seem to be with 9" centres though). Do I buy a truetrac or stick with an Eaton posi?

What's your opinion on the best option for my diff?

Is a 454 big block car, will be TH400, factory 12 bolt, weekend street cruiser, will see 'occasional spirited driving'.

Looking to use 3.42 or 3.55 gears if it makes any difference.
