Differential Lockpin Availability

[slosteve]

So I start what I think will be a simple maintenance project and 'bam', right away something goes awry. I've got a rear axle seal leaking on my '71, so as I'm taking it apart, I remove the differential pinion shaft 'lockpin' and all that comes out is about 1 inch of the threaded part of the bolt - the rest remaining in the hole. I finally get the broken part out and a friend tells me "good luck finding a new one"! Are these items really hard to find?
