Rear end gear question

[68Coupe]

I have some new gears coming in for the rear end but everything I read says I have to use a dial indicator to install them. Has anyone done this without one or does anyone have one I can borrow?

I have never changed gears before but except for having a dial indiator it doesn't look hard. Any comments?

OK, I have been advised by several people to take this somewhere to be done. DOes anyone have any suggestions on a place?
