Default How to measure rear axle length

Bad bearing. Looks like someone put my axle on a metal lathe and cut the width of the bearing. So in trying to find a new axle and I am having some confusion measuring the length of the axle. Which side of the plate do you measure from and to how far down? To the end of the spleene or after the C-clip at the very very end? Also does anyone know of some good places to get these parts?

Here's the usual measurement locations.
Most people use the C or K dimension.

Hook the tape measure on the outer side of the axle flange and measure the TOTAL length of the axle, all the way to the very end. If it's a '67 or older axle then it should be about 29 5/8. If it's a '68 or later axle then it should be about 30 1/8. If you are going to get a new axle then get a pair. Don't use one new axle and one old axle.

Its a 12 bolt Rear for a '70. Not sure if its original or not to be honest. They're right about that 30" 1/8th ish mark depending on the accuracy of the rulers that I've used

Is it possible to install wheel studs yourself? Or do you need a machine shop to press them in?

Use 2 flat washers with grease between them and a nut to pull the studs in place. It might take a while, but you can do it.

Theres 3 bolts broken off that hold the cover on. I've tried a screw extractor to no success. Also tried heating and cooling the bolts to loosen them. Still don't want to budge. Any other ideas?

Put a flat washer over the broken bolt and weld the bolt to the washer. Then weld a nut to the washer and use a wrench to remove the broken bolt. There have been very few times that this didn't work for me.
