Rear ends

Is the 67 Pontiac GTO rear end the same as a GM (ie Chevelle)?

No. The Chevelle was a weaker, c-clipped rear end. You'd want one out of another Pontiac A body, or a Buick or Olds.

You can indeed use a 10 or 12 bolt Chevelle (a-body) rear end in your 67 GTO, you may have to adjust the length of your drive shaft. The control arms should bolt in place.

a 12 bolt in a gto requires a chevelle driveshaft. the u joints are not the same size.

Garage
They do make "conversion" U-joints that will work with you existing driveshaft.

in '79 when I put a 12 bolt in my '64, the most simple n cheap solution was to go to the local junkyard n buy a complete driveshaft from a manual trans. chevelle for $25.00. lol. miss those days !
