rear end widths - The 1947 - Present Chevrolet & GMC Truck Message Board Network

So I've been looking at rear end widths and have done a search for the numbers.

The search resulted in ALOT of wheel back spacing Q&A but thats not what I'm looking for.

So here is the question,,,,,

What is the rear diff width on our trucks? I know the 67-69 is approximately 1.5" narrower than the 70-72's.

I've read somewhere the 70-72s are 64 1/8" from wheel mount to wheel mount. Is this correct?

67-69= 62 5/8" ?
70-72= 64 1/8" ?

Just double checking my double checking before I get myself in trouble.

Thanks guys,
Frank
