What is the rear axle to width on a 69 GTO 10 bolt?

The rear axle width on a 1969 GTO with a 10-bolt rear end varies slightly depending on the options selected. There's no single definitive answer. You'll need to measure the actual axle width of the specific car.

However, a good starting point for a *general* idea is around 57-59 inches. This is a common range, but variations exist due to different axle choices (e.g., different gear ratios might have slightly different widths) and potential modifications over the years.

To get the precise measurement: Measure from the center of one axle flange to the center of the other axle flange. This is the most accurate method.
