Conversion axle install; any tips?

70 swb
75" between backing

-Have the 6 to 5 axles coming this week from EC.

I have never swapped axles before.
I cant find any 67-72 specific axle conversion 'how to' videos.

Is there any special tools I will need?
Will I need (*or should) to replace the differential fluid, if so what weight and how much will I need?
Can anyone point me to a 'good' video of the axle swap? (too many 'how to' vids done with bad info. I cant tell if one is good or not!) OR a site with a 'how to' pictorial.

Thanks for any advice!

Re: Conversion axle install; any tips?

There's a video on You Tube by Sappers House, called ''GM12 Bolt. Removing the Axle''

You will want about a gallon of SAE 90 weight gear oil, service GL-4 if not a Posi and GL-5 if Posi. You don't re-use gear oil.

Every 25 years I like to rebuild that 292, whether it needs it or not.
