[M&M CUSTOM]

I am doing more work on information for here in Hotrodders.

I have the measurements for 64-67, 68-72, and 78-88 GM A/G-body cars.

I need the wheel mounting surface to wheel mounting surface for the 73-77 rear axle.

If there is a difference with the 10 and 12 bolt axles (none of the other generations are different) being a different width let me know that too.

i've seen that link about a hundred times now and it's kind of funny how the 73-77 GM A-body is not included.

Rear axle flange to flange is supposedly wider than the 68-72 AND the 78-88 GM A and G body cars.

I have a source for the axleshafts and the difference in the shafts shows this to be true, BUT doesn't show the diff center pin diameter, OR the total width.

Anyone???

Someone out there has to have one of these cars, half torn apart, or just an axle laying around, and could possibly measure this up for me. I hope.

"it's kind of funny how the 73-77 GM A-body is not included"

Nobody includes the 73-77 A-body in anything unless something is exactly the same as a more "popular" style. I can barely get anything for my car. The stupid suspension companies like Comp don't even make trailing or control arms for it. It's not like they are a lot different than the 64-72, you know? I measured the trailing arms of a 69 GTO last summer and they are almost identical. But I digress.

If you can wait until the end of next month I'll get the measurement off of my 442. I've got the stock 8.5" 10 bolt and 11" drums on it.

It looks like I don't have much of a choice but to wait, I know a couple owners of this generation A-body, but they are all storing their cars for the winter, and not one of them is within reasonable driving distance of me just to check their axle for a couple measurements.
